Odds ratio for in-hospital mortality, 30-day mortality, and 30-day readmission in patients with comorbidity vs multimorbidity, derived from a logistic model

No MCC	2 (3.8)	1
Comorbidity	22 (7.7)	2.12	0.48–9.32	0.318
Multimorbidity	68 (6.4)	1.76	0.42–7.37	0.441
30-day mortality				0.088
No MCC	2 (3.8)	1
Comorbidity	43 (15.0)	4.51	1.06–19.23	0.042
Multimorbidity	130 (12.3)	3.58	0.86–14.90	0.079
30-day readmission				0.227
No MCC	6 (11.7)	1
Comorbidity	44 (22.7)	2.20	0.88–5.50	0.091
Multimorbidity	157 (21.9)	2.11	0.88–5.03	0.093
