What was measured

PPV = proportion of those with a positive test who have neoplasia compared to pathology results

Groups in this outcome

HRME With Proflavine

High Resolution Microendoscopy (HRME) imaging device that operates as a fluorescence microscope with a fiber optic imaging probe. The probe is placed against the mucosa to obtain images relayed to a tablet computer. 0.01% Proflavine hemisulfate used as a fluorescent contrast agent applied topically to mucosa. HRME is used to capture images of suspicious areas sprayed with proflavine hemisulfate.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
