Figure S2. Scatter plot of generator life. Scatter plot of generator life versus amplitude (A), pulse width (B) and frequency (C), All cases were plotted individually. Black line represents regression line. There was a significant inverse correlation between DBS voltage setting and generator life, but not with pulse width or frequency at twelve months (r = − 0,566, p < 0.05, Spearman correlation).
