Multivariate analysis of VT ablation outcomes, in relation to procedure duration, adjusted for baseline covariates

	Unadjusted			Adjusted
	Odds ratio	95% CI	P value	Odds ratio	95% CI	P value
Acute procedural outcome
Acute Success	0.99	0.83–1.19	.92	1.13	0.92–1.4	.24
Acute or partial success	0.96	0.74–1.26	.79	0.99	0.73–1.34	.95
Complications
Hospital mortality	1.6	1.15–2.21	.0051	1.75	1.14–2.68	.0098
Nonlethal post operative complications	1.25	0.97–1.61	.08	1.25	0.96–1.62	.103
Clinical outcomes
Recurrence at 6 months	1.05	0.88–1.27	.57	1.03	0.83–1.28	.79
Survial at 6 months	0.88	0.69–1.11	.27	1.01	0.74–1.39	.93

Odds ratio for outcome per one hour increase in procedure duration. This model adjusts for the most significant of 13 baseline covariates using a stepdown logistic regression method.

CI = confidence interval.
