Glucose levels >88 mg/dL (AUC 0.781, Sn 74%, Sp 75%, PPV 61%, NPV 84%) and insulin levels >11.5 mUI/mL (AUC 0.994, Sn 95%, Sp 94%, PPV 90%, NPV 97%) were the cut-off points that were associated with the development of IR in non-diabetic patients without COVID-19 history (Table 5). The gene discussed is INS; the disease is COVID-19.
