Fig. 3From: Evaluation of circulating insulin-like growth factor-1, heart-type fatty acid-binding protein, and endotrophin levels as prognostic markers of COVID-19 infection severityLinear regression of COVID-19 severity predictive variables with other clinical parameters. Oxygen saturation was found to be inversely correlated with age (A); IGF-1 (B), and H-FABP levels (C), while IGF-1 was positively correlated with H-FABP (D); CRP (E), and ferritin (F). Serum ETP also showed positive correlations with NLR (G) and D dimer (H), and inverse correlations with CRP (I) and procalcitonin (J)Back to article page
