Table 2

(a) Hospital stay in the cholecystostomy and acute cholecystectomy groups. Multivariate linear regression analysis was performed with adjustment for age, gender, Charlson comorbidity index, and degree of cholecystitis. (b) Complication rate in the cholecystostomy and acute cholecystectomy groups. Multivariate logistic regression analysis was performed with adjustment for age, gender, Charlson comorbidity index, and degree of cholecystitis.

Mean hospital stay, days (95% confidence interval)	11.4 (8.9–13.8)	5.1 (4.8–5.4)	6.3 (3.6–9.0)	<0.001	<0.001

(b)

	Cholecystostomy group ()	Acute cholecystectomy group ()	Odds ratio (univariate analysis)	Odds ratio (multivariate analysis)
Complication rate (Clavien-Dindo ≥2)	2 (2.8%)	126 (17.1%)	7.1 (1.7–29.4)	15.1 (3.4–66.8)
