How these tables are computed

The cohort is every profile in the directory tagged to Gastroesophageal Cancer, from the person's registered trials and published research. Only indications with at least 200 tagged people get a page; a smaller cohort would say more about the tag than about the people in it. Each table sorts the cohort by one count, highest first, with no weighting, no blending and no editorial pass. Ties are broken by the profile's stable internal id so the same counts always give the same order. A person with no count on record is left out of that table, not ranked last.

Citations, NIH awards and congress contributions are counts over a person's whole record, not their work in this indication alone, so those three tables are limited to the indication's investigators: people with at least 2 registered trials in it. Without that rule the most cited people in a cohort are the ones whose careers span many diseases, which is a fact about their careers, not about this field. The registered-trials table is the indication-scoped count itself and has no such limit.

The counts are recomputed on every publish and the page carries the date of the publish it was built from. Previous editions are superseded, not archived.

What is deliberately absent

Reported industry payments are on every profile but are not a table here: a count of payers is a fact, and ranking people by it reads as a judgment. Prescribing volume is part of the paid workspace. The directory's influence tier is a judgment and never orders a public page. Sources and methodology.
