Serum BA analysis from HHB and UHB group. (a) Total BA concentrations and major BA ratio of the subjects from the HHB and UHB group. BA species include unconjugated, taurine-conjugated, and glycine-conjugated BAs. The proportions of BA species were calculated as follows: concentrations of BA species / Total BA × 100%. n = 121 in HHB group, n = 62 in UHB group. HHB: healthy high BMI group; UHB: unhealthy high BMI group. **p<0•01 (Mann–Whitney U test). (b) ROC of non-12-OH BAs% in predicting healthy high BMI. AUC: area under curve.
