a
The final reading time of the test was 30 min.
b
Invalid results (5 of a total of 72 samples) were excluded for calculation of sensitivity, specificity, PPV, NPV, and accuracy.
c
There was one invalid result for an H. pylori-positive male patient (38 years old) with no endoscopic abnormalities.
d
There were invalid results for three H. pylori-negative female patients (two with no endoscopic abnormalities [both 62 years old] and one with gastric and duodenal ulcer [63 years old]) and for one H. pylori-positive male patient (64 years old) with gastritis.
