The Efficacy and Predictors of Using GPi-DBS to Treat Early-Onset Dystonia: An Individual Patient Analysis

Figure 3

Potential predictive factors for relative improvement (%) in BFMDRS-M and BFMDRS-D under 3 years of follow-up visit. There were significant positive correlations between (a) disease duration and the relative improvement (%) in BFMDRS-M (Pearson , ), (b) preoperative BFMDRS-M score (, ) and the relative improvement (%) in BFMDRS-M, (c) age at onset (, ) and the relative improvement (%) in BFMDRS-D, and (d) preoperative BFMDRS-M score (, ) and the relative improvement (%) in BFMDRS-D. Dots: individual patient values; black solid line: linear regression line; area between the dotted lines: 95% confidence interval; BFMDRS: Burke–Fahn–Marsden Dystonia Rating Scale; BFMDRS-D: BFMDRS disability subscale; BFMDRS-M: BFMDRS movement subscale.
