GPT and gallstones: Among the physical examinations and blood markers, we noted that weight (odds ratio [OR]: 1.02; 95% confidence interval [CI]: 1.00–1.04; P = .021), ALT (OR: 1.02; 95% CI: 1.01–1.03; P = .001), total SB (OR: 1.04; 95% CI: 1.02–1.06; P < .001), free SB (OR: 1.17; 95% CI: 1.12–1.21; P < .001), TG (OR: 0.76; 95% CI: 0.60–0.97; P = .024), and LDL (OR: 1.59; 95% CI: 1.32–1.91; P < .001) correlated with the risk of developing gallstones.
