Multivariate analysis of predictors of poor outcomes (mortality, invasive mechanical ventilation, ICU admission) among hospitalized patients with SARS-CoV-2 infection at King Saud University Medical City.

	Multivariate OR (95% CI)	P
Predictors of mortality
Initial respiratory rate >24 breaths/min (vs. ≤24 breaths/min)	2.8 (1.1–7.2)	.031
Initial systolic blood pressure <90 mmHg (vs. ≥90 mmHg)	6.0 (1.1–34.0)	.041
Lymphocyte count < 1 × 109 cells/L (vs. ≥1 × 109 cells/L)	2.9 (1.2–7.2)	.020
AST >37 units/L (vs. ≤37 units/L)	3.3 (1.2–9.4)	.026
Predictors of invasive mechanical ventilation
RT-PCR Ct value ≤ 24 (vs. >24)	2.5 (1.1–5.4)	.023
Predictors of ICU admission
Initial systolic blood pressure < 90 mmHg (vs. ≥90 mmHg)	5.9 (1.2–30.0)	.032
AST > 37 units/L (vs. ≤37 units/L)	3.1 (1.2–8.5)	.024
