Table 2 Association between physical activity and high-grade dysplasia/early gastric cancer risk

¹P value for comparison with low physical activity within each model (logistic regression).

²P for trend represents the P value for linear trend across physical activity tertiles in model 3.

³Odds ratios and 95% confidence intervals were estimated using logistic regression. Model 1 was unadjusted. Model 2 was adjusted for age, sex, marital status, education, occupation, household income, smoking, alcohol consumption, dietary habits (hot food, fast eating, fried food), body mass index, Helicobacter pylori infection, medical history (gastritis, peptic ulcer, gallbladder disease, gastric polyps), and family history of gastric cancer. Model 3 was additionally adjusted for total energy intake.

OR: Odds ratios; CI: Confidence interval.
