Figure 1.Comparison between early-onset PD patients with diphasic dyskinesia and early-onset PD patients without dyskinesia. Compared with early-onset PD patients without dyskinesia, early-onset PD patients with diphasic dyskinesia showed higher GM volumes in right precentral gyrus (Cluster size: 162 mm3). Correction for multiple comparisons (family-wise error rate (FWE), P < 0.05) was used to threshold the analysis. Abbreviations: PD, Parkinson’s disease; GM, gray matter.
