%BF, percent body fat; MHN, metabolically healthy normal weight; MHOW, metabolically healthy overweight; MHO, metabolically healthy obesity; MUN, metabolically unhealthy normal weight; MUOW, metabolically unhealthy overweight; MUO, metabolically unhealthy obesity; OR, odds ratio; CI, confidence interval. ^†Multivariable model was adjusted for age (except for age subgroups), sex (except for sex subgroups), race and ethics, education level, smoking status (except for smoking status subgroups), alcohol consumption, physical activity (except for physical activity subgroups), daily water intake, CKD stage 3–5, and hyperuricemia.
