Table 8 Sensitivity logistic regression analysis for intestinal metaplasia detection including study period

Variable	OR (95%CI)	P value
Gastroenterologist vs general surgery	1.08 (0.87-1.33)	0.511
Number of biopsy fragments	1.13 (1.08-1.18)	< 0.001
Study period 2019-2022 vs 2015-2018	1.03 (0.86-1.23)	0.767
Study period 2023-2025 vs 2015-2018	0.61 (0.50-0.75)	< 0.001

The 2015-2018 period was used as the reference category. The model included endoscopist specialty, biopsy sampling intensity (number of biopsy fragments), and study period. OR: Odds ratio; CI: Confidence interval.
