Fig. 2: Brain atrophy patterns of the PD clusters adjusted for global atrophy.
From: MRI subtypes in Parkinson’s disease across diverse populations and clustering approaches

PD brain atrophy patterns compared to the HC group. The maps represent an average across the right and left hemispheres. Cohen’s d values were calculated and are presented in the figure when the FDR-adjusted p value of the ANCOVA reached <0.05. Darker red indicates more atrophy in the PD cluster than in HC. Results were adjusted for age.
