Its location was 70.7% in the upper third of the stomach, 29.3% in the middle third and none in the lower third. Histologically, this lesion had a mucus pool within a dilated duct surrounded by flattened glandular epithelium. The cumulative incidence rate of stardust gastric mucosa at 1, 2 and 3\u00a0years was 4.6%, 16.5% and 26.2%, respectively. The factors independently associated with the presence of stardust gastric mucosa were &gt;205\u00a0days of vonoprazan oral intake (odds ratio [OR]: 6.99, 95% confidence interval [CI]:
