  1. Variables marked with are presented as median (interquartile range), all others are presented as mean (standard deviation).
  2. HDL-cholesterol: high density lipoprotein cholesterol; LDL-cholesterol: low density lipoprotein cholesterol; ACR: albumin-to-creatinine ratio; AUC glucose: area under the curve of glucose levels across 2 hours of a standard oral glucose tolerance test.
