HMOX1 and hyperlipidemia: After stratifying age and BMI subgroups, respectively, by gender and adjusting potential confounding factors, we found a significant negative correlation between high levels of HO-1 and hyperlipidemia in the overweight group within female subjects, while for male participants, whether in the normal weight or overweight subgroup, no statistically significant relationship between HO-1 and hyperlipidemia was observed (OR, 0.4; 95% CI, 0.21–0.84; p = 0.014).
