Predictors of Lead failure
A univariate logistic regression analysis of the whole study population
was performed for predictors of lead failure (table3 ). Female gender (p=0.02, OR 4.42, [1.258-15.51]) and BMI
(p=0.03, OR 1.12 [1.01-1.24]) were significant factors whilst
hypertension was strongly correlated although it did not reach
statistical significance (p=0.055, OR 7.62 [0.96-60.5]). When
entered in to a Cox regression analysis, female gender (p=0.007 OR 7.32
[1.7-31.1]), hypertension (p=0.041, OR 9.96 [1.1-90.5]) and BMI
(p=0.042, OR 1.12 [1.004-1.24]) were significant predictors of lead
failure.
