A logistic regression model ( p = 0.013, R2 = 0.219) correctly classified 63.2% of cases, with no significant predictors of PLE, but imaging complications ( p = 0.057) and electrode brand ( p = 0.086) approached significance, with Boston Scientific electrodes linked to higher PLE risk compared to Abbott electrodes ( p = 0.027, OR = 3.729).
Additionally, while longer operative time and increased microelectrode recordings (MERs) per electrode showed a trend towards higher risk, these factors did not reach statistical significance [ 8 ].
STN placements, although not statistically significant, showed a trend toward significance with PLE, suggesting that this target site may predispose patients to developing PLE more than other commonly targeted regions, such as VIM or GPi.
