Fig. 3.

Time courses of mean MEP size ratio after QPS5. Diamonds (◆), circles (○) and squares (■) represent “PD without L-DOPA”, “PD with L-DOPA” and healthy controls (HC), respectively. The x-axis indicates time points after QPS5 and the y-axis MEP size ratio. Two-way repeated-measure ANOVA showed a significant effect of the factor “GROUP”, but not of the factor “TIME”. The post hoc analysis showed significant differences between “PD without L-DOPA” and “PD with L-DOPA” and between “PD without L-DOPA” and HC, but not between “PD with L-DOPA” and HC. Error bars are 1 SEM.
