In Model A and Model B, systolic blood pressure or diastolic blood pressure were considered, respectively. In Analysis I and Analysis II, body mass index (z-score) or waist-to-height ratio were considered, respectively. The coefficient β provides a measure of the relative strength of the association independent of the units of measurement. BMI, body mass index; BP, blood pressure; CI, confidence interval; eGFR, estimated glomerular filtration rate; HOMA, homeostatic model assessment; WtHr, waist-to-height ratio.
