Stepwise Logistic Regression Analysis

Variable	Odds Ratio	CI 95%	P value
Age	1.2	1.004–1.32	0.04
Chest discomfort	2.7	1.6–4.7	<0.001
Medications before ablation	1.8	1.4–2.3	<0.001
ECG pre‐excitation	…	…	0.89
Average number of concomitant symptoms	…	…	0.81
Time between symptoms and ablation	…	…	0.72
Life long emergency room evaluations	…	…	0.64
Palpitation	…	…	0.56

Dyspnea	…	…	0.23

Result of stepwise logistic regression analysis showing the odds ratio of each independent predictor variable and the 10 variables retained in the model. Medications before the ablation were considered the use of antiarrhythmic medications prescribed to avoid new supraventricular tachycardias episodes.
