Analysis of the prognostic factors of mortality in COVID-19.

Variables	AUC	Cut-off point	Sensitivity	Specificity	p
PhA	0,839	3.95	93.8%	66.7%	0,001
SPhA	0,779	−1.85	75%	75.7%	0,005
Prealbumin	0,769	13.55	72.7%	77%	0,005
Lymphocytes	0,801	1075	75%	73.9%	0,000
CRP	0,783	62.75	68.8%	82.7%	0,003

PhA: phase angle; SPhA: standardized phase angle; AUC: area under the curve; CRP: C-reactive protein.

Evaluation of prognosis factors of mortality in COVID-19 based on the area under the curve (AUC) of the receiver operating characteristic (ROC) curve, and sensitivity, specifity values to determine the optimal cut-off values.
