Methods, Coverage & Corrections

How every figure on the Map is counted, where it comes from, and what it does not measure.

Data Dates

Three Record Types

Publications, clinical trials and observational studies are three record types, shown apart and never added together. Publications have at least one Saudi-affiliated author and count in the year of their earliest publication date. Clinical trials and observational studies list at least one Saudi site in ClinicalTrials.gov and count in their recorded start year, actual or estimated; withdrawn studies and expanded-access records are not counted. A listed site does not prove that participants were recruited in Saudi Arabia. Papers linked to a registration through their own registration number are a lower bound, and the overlap is never subtracted from any count.

Journals that follow ICMJE policy require clinical trials to be registered before enrolment begins, in ClinicalTrials.gov or another accepted registry; observational studies have no such requirement, so registered observational studies are a small, selective part of observational research. These figures count studies recorded in ClinicalTrials.gov; they do not measure total research volume, study completion or financial investment.

Study Types & Industry Involvement In Papers

Each paper's study type and its industry involvement are classified by AI under published guides. Industry involvement is identified from the paper's own record and registration; it does not establish financial investment and is a lower bound. The industry code has four values: industry-involved, author ties only, no industry link and no statement; "no statement" is never merged with "no industry link".

Industry In Registrations

A study is industry-led when its lead sponsor is a health-product company, or a contract research organisation with one as collaborator, decided from one reviewed list of sponsor names. ClinicalTrials.gov's "industry" class is only a guide. Industry in papers and industry in registrations are different measures of different records and are never combined.

On Clinical Studies & Industry, each industry-led study is credited to one company, exactly as the industry-led counts decide it: its lead sponsor or, for a contract research organisation's study, its company collaborator listed in the registration, so the companies' studies add up to the industry-led totals. Company names are shown as registered, with no grouping into parent companies, and only studies listing a Saudi site are counted. The counts describe registered activity; they do not measure investment or quality.

Each company's trials worldwide come from a separate pull: the interventional trials each company leads under the same registered name, started 2021–2025, with withdrawn studies and expanded-access records left out, as in the Saudi count. Only exact matches of the registered name are kept, and trials a contract research organisation runs for a company are counted on neither side. The share listing a Saudi site is the company's trials listing a Saudi site over its trials worldwide, to one decimal place; it describes where trials are registered and does not measure investment, commitment or quality. No worldwide count is given for observational studies.

Clinical trials are shown by ClinicalTrials.gov's intervention type, read in a separate pull of two fields. A trial with several intervention types counts in each, so the types are never added together; “Other” is the registry's own type. Observational studies are not shown by type.

On each area profile, the companies and institutions are counted for that area only: each company's industry-led studies in the area add up to the area's industry-led counts, and each institution's publications, clinical trials and observational studies are counted exactly as on Institutions & Clusters, narrowed to the area. A study or a paper in several areas counts in each.

Principal Investigators In Trial Records

A clinical trial's record shows a principal investigator only when the registration lists that person as an overall official with the role of principal investigator and an affiliation that is Saudi: it matches the reviewed Saudi facility or institution lists, or it names Saudi Arabia or a Saudi city. The name is shown as registered and the affiliation by its reviewed name; an affiliation that names Saudi Arabia or a Saudi city but matches no reviewed list is shown as “Saudi institution not identified”.

Study chairs and directors, contacts, investigators with no Saudi affiliation and anyone on an observational record are never shown. No list, count, page, chart or search covers a person. The overall officials were read from ClinicalTrials.gov on 8 November 2026, in a separate pull of four fields: each study's number and each official's name, affiliation and role. A person who asks to be removed is removed through the comment form below.

Citation Measures

Mean field-weighted citation impact and the share in the world's most cited tenth come from OpenAlex, with fractional counting, by OpenAlex publication year: nothing for the newest year, which has no citation window, and the two years before it provisional. Each carries a stability interval, shown as its two ends, and a measure is hidden when fewer than 50 papers carry it.

Health Areas & Disease Burden

Papers and studies reach the seventeen areas named by SNIH through their subject headings, by the SNIH research dictionary; papers without MeSH terms can't be assigned. Burden comes from WHO Global Health Estimates through the WHO cause-to-area table, with each area rated a close match, partial or not directly comparable; the research-share-to-burden-share ratio is shown only for close-match areas that pass the cause table's test.

Institutions & Clusters

Institutions are named as OpenAlex records them and listed largest first, with a switch to A–Z, and no rank numbers. A parent institution's row also counts its units' records. Health clusters follow the Health Holding Company's facility list; industry-led trials are shown with an activity band. Institution and sector matching: not measured; examples reviewed.

The SNIH Area Dictionary

How papers and registered studies reach the seventeen areas: each area's subject headings, by their MeSH tree numbers. A paper belongs to an area when any of its subject headings is one of these or sits beneath it.

The WHO Cause-To-Area Table

How disease burden from WHO Global Health Estimates reaches the seventeen areas: each area's WHO causes, its sex and age limits and its rating; then every cause row, and every WHO cause with the areas it reaches.

Areas
Order in SNIH's listAreaComparabilityWHO causes included (GHE code: cause)Number of cause rowsSex and age limitsWhat it covers and known differences
1Cardiovascular DiseasesClose match1100: Cardiovascular diseases; 1440: Congenital heart anomalies (shared)2Both, All agesAll of WHO's cardiovascular group, including stroke. Known difference: vascular neoplasms sit in C14 but their burden is inside WHO 780 Other malignant neoplasms and 790 Other neoplasms; subject to the 10% test. 10% test rows: 780, 790.

WHO 814 also includes blood and immune conditions outside C18 and C19 (extra scope). Obesity has no separately usable WHO burden total.
3CancerClose match610: Malignant neoplasms; 790: Other neoplasms2Both, All agesAll malignant and other neoplasms. Known difference: precancerous oral lesions (leukoplakia) sit in C04 but their burden is inside WHO 1502 Other oral disorders; subject to the 10% test. 10% test row: 1502.
4Rare and Inherited DiseasesPartial811: Thalassaemias; 812: Sickle cell disorders and trait; 813: Other haemoglobinopathies and haemolytic anaemias; 1400: Congenital anomalies; 1370: Gout (shared)5Both, All agesHaemoglobinopathies, all congenital anomalies and gout (MeSH convention). WHO 813 also includes acquired haemolytic anaemias (extra scope). Most other rare and inherited diseases have no separate WHO cause.
5Infectious DiseasesClose match20: Infectious and parasitic diseases; 390: Lower respiratory infections; 395: COVID-19; 400: Upper respiratory infections; 520: Neonatal sepsis and infections (shared); 1110: Rheumatic heart disease (shared)6Both, All agesInfectious and parasitic diseases, respiratory infections (including COVID-19), neonatal infections and rheumatic heart disease. Known differences: WHO 410 Otitis media combines conditions whose MeSH coverage differs, and the infectious subset cannot be isolated from it; infectious parts of 1330 Skin diseases and 1150 Cardiomyopathy, myocarditis, endocarditis are also unresolved partial matches. 10% test rows: 410, 1330, 1150.
6Population and Public HealthNot directly comparable—0—Not mapped in the research dictionary either. The page shows 'burden not directly comparable'.
7Neurological DiseasesPartial940: Neurological conditions; 1140: Stroke (shared); 170: Meningitis (shared); 180: Encephalitis (shared); 751: Brain and nervous system cancers (shared); 1410: Neural tube defects (shared); 920: Idiopathic intellectual disability (shared); 1430: Down syndrome (shared); 1080: Other hearing loss (shared)9Both, All agesAll of WHO's neurological group, plus the topics MeSH also files under Nervous System Diseases (C10). Partial because C10 includes brain and spinal cord injury research, while WHO records injury burden by external cause; road-injury and fall burden is not allocated to this area.
8Kidney DiseasesClose match1270: Kidney diseases; 1290: Urolithiasis; 745: Kidney, renal pelvis and ureter cancer (shared)3Both, All agesKidney diseases (including chronic kidney disease due to diabetes), urinary stones and kidney cancer. 10% test rows: 1290 and 745 (broader proxies).
9Lung DiseasesClose match1170: Respiratory diseases; 390: Lower respiratory infections (shared); 395: COVID-19 (shared); 400: Upper respiratory infections (shared); 680: Trachea, bronchus, lung cancers (shared); 753: Larynx cancer (shared); 30: Tuberculosis (shared); 130: Whooping cough (shared)8Both, All agesRespiratory tract diseases (C08 covers the upper respiratory tract as well as the lungs): chronic respiratory diseases, respiratory infections, whooping cough, lung and larynx cancers, and tuberculosis. Known difference: cystic fibrosis sits in C08 (and C06), but its burden is inside WHO 814. 10% test rows: 30 (broader proxy) and 814 (omitted scope).
10Gastrointestinal and Liver DisordersClose match1210: Digestive diseases; 110: Diarrhoeal diseases (shared); 185: Hepatitis (shared); 630: Oesophagus cancer (shared); 640: Stomach cancer (shared); 650: Colon and rectum cancers (shared); 660: Liver cancer (shared); 670: Pancreas cancer (shared); 752: Gallbladder and biliary tract cancer (shared)9Both, All agesDigestive diseases, diarrhoeal diseases, acute hepatitis and digestive cancers. Known difference: cystic fibrosis sits in C06 (and C08), but its burden is inside WHO 814; subject to the 10% test. 10% test row: 814.
11Newborn, Child, and Adolescent HealthPartial (by age)0: All causes1Both, Ages 0–19Burden by age: every DALY at ages 0–19 (WHO age groups; MeSH's Adolescent group ends at 18). Partial because the research side (dictionary v1.2) includes papers on children together with adults, and newborn-disease headings (C16.614) that don't establish participants' ages; a label distinguishes 'children only' papers from 'children and adults'.
12Dental and Craniofacial DiseasesPartial1470: Oral conditions; 1420: Cleft lip and cleft palate (shared); 620: Mouth and oropharynx cancers (shared)3Both, All agesOral conditions, cleft lip and palate, and mouth and pharynx cancers. Partial because C07 also includes pharyngitis and tonsillitis, whose burden sits inside WHO 400 with conditions outside C07 (unresolved partial match).
13Women's HealthClose match420: Maternal conditions; 1320: Gynecological diseases; 700: Breast cancer (shared); 710: Cervix uteri cancer (shared); 720: Corpus uteri cancer (shared); 730: Ovary cancer (shared); 1310: Infertility7Female, All agesPregnancy complications, female genital diseases (including female cancers and infertility) and breast cancer, women only. It does not cover all illness in women. Dictionary v1.2 leaves male breast neoplasms and gynaecomastia out of this area, so research and burden both cover women only.
14Musculoskeletal, Skin, Pain, and AutoimmunePartial1340: Musculoskeletal diseases; 1330: Skin diseases; 690: Melanoma and other skin cancers (shared); 980: Multiple sclerosis (shared)4Both, All agesMusculoskeletal and skin diseases, skin cancers and multiple sclerosis. Omitted overlaps: other autoimmune conditions and most pain conditions have no separate WHO cause; C17 also includes cutaneous leishmaniasis and onchocerciasis (WHO 260 and 280, not added because their WHO totals include non-skin disease).
15Mental DisordersClose match820: Mental and substance use disorders; 1610: Self-harm (shared); 950: Alzheimer disease and other dementias (shared)3Both, All agesMental and substance use disorders, self-harm and dementia. Known difference: F03 includes sleep–wake disorders, whose burden sits inside WHO 1010 Other neurological conditions (unresolved). 10% test row: 1010.
16Eye DiseasesClose match1030: Glaucoma; 1040: Cataracts; 1050: Uncorrected refractive errors; 1060: Macular degeneration; 1070: Other vision loss; 310: Trachoma (shared)6Both, All agesGlaucoma, cataracts, refractive errors, macular degeneration, other vision loss and trachoma. Known difference: WHO 1090 Other sense organ disorders mixes eye and ear conditions and stays unallocated. 10% test row: 1090.
17Deafness and Other Communication DisordersPartial1080: Other hearing loss; 410: Otitis media (shared); 400: Upper respiratory infections (shared); 753: Larynx cancer (shared); 622: Nasopharynx (shared); 623: Other pharynx (shared)6Both, All agesHearing loss and ear, nose and throat conditions with a WHO cause. No separately extractable WHO total matches the dictionary's speech and language scope. Unresolved components inside 1090, 1200 and 930.

PubMed and MeSH, U.S. National Library of Medicine

Used for: the publication records, their titles and their MeSH terms.

  • The Map acknowledges the U.S. National Library of Medicine as the source with the credit line below, here and in the research-sources line at the foot of every page.
  • Showing these records does not mean that the National Library of Medicine endorses the Map.
  • The Map uses the dated PubMed snapshot given under Data Dates, so it does not reflect the most current data available from the National Library of Medicine.
