Un-standardized and standardized regression coefficients of log-transformed Zn and Se to log-transformed of covid-19 severity score in simple and multivariable * regression

	Independent variables	Unstandardized coefficient (95% CI)	SE	Standardized coefficient	P value
Simple linear	Zinc, mcg/ml, log	− 0.36 (− 0.66, − 0.07)	0.15	− 0.26	0.02
Regression	Se, mcg/ml, log	− 0.33 (− 0.57, − 0.08)	0.13	− 0.28	0.01
Multiple linear	Zinc, mcg/ml, log	− 0.12 (− 0.44, 0.21)	0.16	− 0.09	0.46
Regression	Se, mcg/ml, log	0.07 (− 0.2, 0.33)	0.13	0.07	0.62

*Analyses were controlled for the following covariates: age, and log-transformed of Urea, CRP, INR, VB 12, lymph, Hb, Cr, troponin, and d-dimer
