Multivariable-adjusted odds ratios of metabolic syndrome according to levels of estimated glomerular filtration rate. An eGFR of 60 ml/min/1.73m², as a reference value of decreased renal function, was taken as the reference point (OR = 1.00). The adjusted OR of MS was significantly increased at eGFR levels of < 60 ml/min/1.73m². The model was adjusted for age, sex, eGFR, and overt proteinuria. The solid line represents the multivariable-adjusted ORs of MS according to levels of eGFR. The dashed lines indicate 95% confidence intervals. eGFR, estimated glomerular filtration rate; OR, odds ratio; MS, metabolic syndrome
