Diagnostic yield and biopsy practice variability between gastroenterologists and general surgeons performing upper gastrointestinal endoscopy

Table 6 Multivariable models for predictors of intestinal metaplasia

Variable	Model 1, OR (95%CI)	P value	Model 2, OR (95%CI)	P value
Gastroenterologist endoscopist	1.23 (1.00-1.52)	0.051	1.14 (0.92-1.41)	0.23
Age	1.03 (1.03-1.04)	< 0.001	1.04 (1.03-1.04)	< 0.001
Female sex	0.80 (0.68-0.92)	0.003	0.79 (0.68-0.92)	0.002
Helicobacter pylori	2.06 (1.76-2.42)	< 0.001	1.48 (1.26-1.74)	< 0.001
Number of biopsy fragments	-	-	1.03 (0.99-1.07)	0.10

Model 1 was adjusted for age, sex, and Helicobacter pylori infection. Model 2 additionally included biopsy sampling intensity (number of biopsy fragments). OR: Odds ratio; CI: Confidence interval.
