Clinical variables associated with clinical deterioration in the final model of the multivariable stepwise logistic regression analysis

Clinical variables	Adjusted odds ratio (95% CI)	p‐value
Cycle threshold value <25	7.05 (3.06–16.4)	<.001
Elevated C‐reactive protein	3.04 (1.44–6.45)	.004
Age >50 years	2.88 (1.28–6.51)	.011
Elevated creatine kinase	3.13 (1.22–8.03)	.017
Non‐thyroidal illness syndrome	3.19 (1.23–8.26)	.017
Nausea/vomiting	4.47 (0.87–22.8)	.072

The model included non‐thyroidal illness syndrome, age >50 years, hypertension, diabetes, stroke/transient ischaemic attack, fever, cough, nausea/vomiting, cycle threshold value <25, lymphopenia, estimated glomerular filtration rate <60 ml/min, elevated aspartate aminotransferase, elevated creatine kinase and elevated C‐reactive protein.

Values reaching statistical significance are in bold.

Abbreviation: CI, confidence interval.
