Hazard ratios (HRs) and odds ratios (ORs) for variables with significant predictive value for hospitalization in the outpatient telemedicine cohort.

Variable	Unadjusted HR (95% CI)	P value	Adjusted HRa (95% CI)	P value	Adjusted ORb (95% CI)	P value
Tier 1	Reference	N/Ac	Reference	N/A	Reference	N/A
Tier 2	5.29 (1.53-18.32)	.009	3.74 (1.06-13.27)	.04	4.87 (1.35-17.57)	.02
Tier 3	16.24 (4.74-55.59)	<.001	10.87 (3.09-38.27)	<.001	15.38 (4.21-56.20)	<.001
Aged ≥60 years	3.77 (1.94-7.34)	<.001	2.53 (1.27-5.02)	.008	2.94 (1.38-6.25)	.005
Reported obesity	2.27 (1.17-4.41)	.02	2.09 (1.06-4.13)	.03	2.17 (1.01-4.67)	.048
Male	1.76 (0.91-3.43)	.10	Analyzed by strata	N/A	1.94 (0.91-4.18)	.09

^aCox overall model of fit: χ²₄=41.4; P<.001.

^bLogistic regression overall model of fit: χ²₅=50.8; P<.001.

^cN/A: not applicable; P value was not calculated because the variable was used as the reference (in the case of Tier 1) or because the variable was analyzed by strata (in the case of gender).
