Table 3. . Multivariate analysis of predictors of positive RT-PCR test for SARS-CoV-2.

Variable	Analyzed as	OR (95% CI)	p-value
CKD-EPI	≥median vs <median	0.59 (0.13–2.52)	0.472
AST	≥median vs <median	5.98 (1.41–33.4)	0.023
White blood cell count	≥median vs <median	0.28 (0.06–1.13)	0.081
LUSS	≥median vs <median	6.97 (1.52–51.1)	0.024
Body temperature (°C)	≥median vs <median	51.4 (10.6–442)	<0.001

Data are reported as number of patients (%) or median (IQR), as appropriate. p-values are obtained using simple logistic regression analysis, dichotomizing each quantitative explanatory variable about its median value.

AST: Aspartate transaminase; CKD-EPI: Chronic Kidney Disease Epidemiology Collaboration; IQR: Interquartile range; LUSS: Lung ultrasound score; OR: Odds ratio.
