  1. Data are expressed as mean ± SD, median with IQR, or percent frequency, as appropriate. Bold values are statistically signifcant.
  2. BMI—body mass index; CRP—C reactive protein; DBP—diastolic blood pressure; eGFR—estimated glomerular filtration rate; HbA1c—glycated hemoglobin; HDL—high-density lipoprotein; LDL—low-density lipoprotein; SBP—systolic blood pressure.
