Comparison of AUROC, sensitivity and specificity of HbA1c%, serum IL-6 levels and BMI in predicting DKA in patients with T2DM and COVID-19 infection receiving glucocorticoids.
| Parameter | AUROC (CI) | Cut-off | Sensitivity (%) | Specificity (%) | Youden’s index | LR |
|---|---|---|---|---|---|---|
| IL-6 levels at admission (pg/ml) | 0·93 (0·89–0·98) | 50·95 | 88 | 85·2 | 0·73 | 5·95 |
| HbA1c (%) | 0·86 (0·75–0·94) | 8·35 | 84 | 72·2 | 0·56 | 4·51 |
| BMI (kg/m2) | 0·84 (0·76–0·93) | 25·56 | 87·6 | 68 | 0·56 | 2·73 |
AUROC = Area under Receiver Operating Characteristic Curve, CI = Confidence Interval, BMI = Body Mass Index, LR = Likelihood ratio.
