Table 6. ROC analysıs of laboratory parameters for use in COVID-19 severity monitoring plan.

Laboratory parameter	Cut-off value	AUC	p value	95% CI (lower bound- upper bound)	Sensitivity %	Specificity %
RDW-CV, %	13.65	0.734	0.001	0.634-0.834	95	66
MPV, fl	11.05	0.711	0.004	0.538-0.840	55	81
PVI	0.057	0.745	0.001	0.627-0.864	80	65

ROC = receiver operating characteristic curve; AUC = area under curve; 95% CI = 95% confidence interval; RDW = red cell distribution width; MPV = mean platelet volume; PVI = platelet volume index
