Variables	OR	95% CI	P
Female sex	1.70	1.35-2.15	< 0.001
Age (yr)
40 to 64	2.44	1.88-3.17	< 0.001
≥ 65	5.83	4.02-8.44	< 0.001
FBG ≥ 1260 mg/L	2.12	1.31-3.43	0.002
Triglycerides ≥ 1500 mg/L	1.67	1.31-2.13	< 0.001

The dependent variable was the presence or absence of gallstone disease. The covariates included sex, age of 40-64 and ≥ 65 years, BMI ≥ 25.0 kg/m², high blood pressure (SBP ≥ 40 mmHg or DBP ≥ 90 mmHg or a history of hypertension), an FPG level between 1100 and 1260 mg/L and ≥ 1260 mg/L, a triglyceride level ≥ 1500 mg/L, an HDL level ≥ 350 mg/L in men or ≥ 390 mg/L in women, a total cholesterol level ≥ 2200 mg/L, and an LDL level ≥ 1550 mg/L.
