Variables associated with severe COVID-19 outcomes in the final model of the multivariable stepwise logistic regression analysis.

Variables	Adjusted OR (95% CI)	P-value
NTIS	3.64 (1.49 – 8.91)	0.005
Male (vs female)	2.20 (1.05 – 4.61)	0.037
IHD/CHF	3.23 (0.91 – 11.5)	0.070
Stroke/TIA	5.49 (1.32 – 22.9)	0.019
Ct value <25	3.34 (1.47 – 7.58)	0.004
Elevated CRP	3.70 (1.51 – 9.10)	0.004
Hypoalbuminaemia	2.12 (0.92 – 4.89)	0.078
Elevated creatine kinase	2.28 (0.95 – 5.45)	0.065

NTIS, non-thyroidal illness syndrome; IHD, ischaemic heart disease; CHF, congestive heart failure; TIA, transient ischaemic attack; Ct, cycle threshold; CRP, C-reactive protein.

The model included NTIS, lymphopenia, age >50 years, male, hypertension, diabetes, obesity, IHD/CHF, stroke/TIA, symptomatic presentation, Ct value <25, hypoalbuminaemia, hyponatraemia, elevated urea, estimated glomerular filtration rate <60 mL/min, elevated aspartate aminotransferase, elevated lactate dehydrogenase, elevated creatine kinase and elevated troponin T.
