Table 1: Demographic data of the study and external validation groups.
Data are expressed as mean ± SD. Ext val group: external validation group HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; HOMA-IR and HOMA-β: homeostasis model assessment of insulin resistance and β–cell function.
