Number of adequately exposed gastric sites
Biomarker1 paper4 findings
In one human study, more adequately exposed gastric sites are associated with greater detection of precancerous conditions, focal lesions and early gastric cancer, but not a statistically significant increase in gastric neoplastic lesion detection.
