Statistical analysis
Continuous variables were expressed as mean ± SD. Categorical data were
expressed as frequencies and percentages. Two-sided p-values <
0.05 were considered statistically significant.
To assess long-term predictors of mortality after TLE, the Cox
proportional hazards regression model was used. The statistical models
were adjusted for typical risk factors and potential baseline
confounders including sex, age, type of the extracted device, indication
for the extraction, major complications, procedural failure,
cardiovascular risk factors.
Statistical analysis was performed using SPSS Version 23.0.0
(Statistical Package for Social Sciences Inc.) and STATA 17.0 software
(Stata Corporation, College Station, TX, USA).
