Why a small condition index still matters
Thin indexes still surface the registry rows that exist for this label. Counts stay small when ClinicalTrials.gov lists few studies under the condition string, not because this page omits rows. Verify any enrollment decision on ClinicalTrials.gov and with a clinician.
