Analysis of the ROC curve of the triglyceride level, HDL c and the Tg/HDL c ratio for the requirement of invasive mechanical ventilation in patients with COVID-19. Fig. 1: The value of p was derived from ∗ Chi squared test, ∗∗ Fisher's exact test. Statistical significance p < 0.05. Abbreviations: AUC, Area under the curve; CI, Confidence interval; HDL c, High-density lipoprotein cholesterol; ROC, Receiver-Operating Characteristic; TG, Triglyceride; Tg/HDL c, Triglyceride/High-density lipoprotein cholesterol ratio.
