Number of participants that the trial has enrolled

498

Results

Significantly higher diagnostic odds were obtained for
RAC (32.2), FGP (7.7), and red streak (4.7) in subjects with noninfection,
map-like redness (12.9) in subjects with past infection,
and diffuse redness (26.8), mucosal swelling (13.3), sticky mucus
(10.2) and enlarged fold (8.6) in subjects with current infection.
The overall diagnostic accuracy rate was 82.9% with the Kyoto
classification of gastritis.

Baseline Characteristics

In this prospective study, 498 subjects were
recruited. Seven well-experienced endoscopists blinded to the
history of eradication therapy performed the examinations.

Participant flow

In this prospective study, 498 subjects were
recruited. Seven well-experienced endoscopists blinded to the
history of eradication therapy performed the examinations.

Adverse events

none

Outcome measures

The correlation of each of the 16 endoscopic features with
the three H. pylori infection statuses (current infection, noninfection,
past infection) was analyzed. Sensitivity, specificity,
positive predictive value (PPV), negative predictive
value (NPV), and diagnostic odds ratio (DOR)19 were
calculated.
