Risk factors	β parameter	Odds ratio (95 % CI)	p-value	Weight
Intercept	−4.91
Age (years)
>45 vs. ≤45	0.76	2.1 (1.1–4.2)	0.03	1
Sex
Male vs. female	0.88	2.4 (1.3–4.4)	0.004	1
No. of comorbidities
≥3 vs. <3	0.80	2.2 (1.2–44)	0.02	1
Pneumonia	0.65	1.9 (1.1–3.5)	0.03	1
Confusion	1.35	3.9 (1.6–9.1)	0.002	2
Dyspnea	1.50	4.5 (1.95–11)	0.0009	2
AUC		0.77
Hosmer–Lemeshow p-valuea		0.9618

CI, confidence interval; β parameter = estimated β coefficient; AUC, area under the receiver operating characteristic curve

All risk factors were examined jointly

^aA significant value for the Hosmer–Lemeshow statistic indicates a significant deviation between predicted and observed outcomes
