Data are number of observarion (n) and correlation coefficients (r). BMI (body mass index), RRS (systolic blood pressure), RRD (diastolic blood pressure), SI (insulin sensitivity index derived from the FSIGT), OGIS (oral glucose tolerance index derived from the OGTT), ΔAIRG (acute insulin response to glucose derived from the FSIGT), IGI (insulinogenic index), HDL (high density lipiprotein), LDL (low density lipoprotein), usCRP (ultrasensitive C-reactive protein), IL-6 (interleukin-6), PAI-1 (plasminogen activator inhibitor 1).

*Spearman’s rank correlation as used instead of Pearson’s product moment correlation due to nonlinear monotonic associations or outliers.
