Based on the sex-specific quartiles among controls. Odds ratios (95% CIs) were adjusted for age, BMI, Waist-Hip Ratio, pack-years, fasting hour, and baseline disease of hypertension and diabetes.
Only metabolites with raw p-trend<0.05 or p<0.01 for the highest quartile in any subgroups of subjects are shown in the table. After FDR adjustment, all p values >0.10.
