Table 2.

Number of patients and risk of emergency department visit or unplanned hospitalization for cardiovascular disease

Time interval	Number of patients	Risk (%) (95% CI)	aOR (95% CI)^a	P-value
ED visit or unplanned hospitalization^b	(n = 11 106)
13–24 months before bariatric surgery	2284	20.6 (19.8–21.3)	Reference	–
1–12 months before bariatric surgery	2259	20.3 (19.6–21.1)	0.98 (0.93–1.04)	0.42
0–12 months after bariatric surgery	2096	18.9 (18.1–19.6)	0.91 (0.86–0.96)	0.002
13–24 months after bariatric surgery	1937	17.4 (16.7–18.2)	0.84 (0.79–0.89)	<0.001

aOR, adjusted odds ratio; CI, confidence interval; ED, emergency department.

Adjusted odds ratios are for each 12 months of period vs. the reference period (i.e. 13–24 months before bariatric surgery), as calculated with conditional logistic regression.

Composite of at least one ED visit or unplanned hospitalization for cardiovascular disease.
