Statistical Analysis.
The primary indications for S-ICD implantation across all study
participants were analyzed. Study participants were then categorized
into two groups based on whether they underwent S-ICD extraction.
Univariate analyses were completed using chi-square or Fisher exact
tests for categorical variables, and Student’s T Tests or Mann-Whitney U
Tests for continuous variables as appropriate. Â Preprocedural variables
with a p value of <0.05 on univariate analysis and those with an
a priori association with device extraction were included in a
multivariate model. Subgroup analyses were performed within cohorts
based on indication for extraction. All statistical analyses were
conducted using SPSS Version 26 (IBM, Armonk, NY).
