Fig. 2: Mass univariate analysis: significant vertex-wise differences in thickness between HY stage and age- and sex-matched controls.
From: A worldwide study of subcortical shape as a marker for clinical staging in Parkinson’s disease

A HY1, B HY2, C HY3, and D HY45 results are shown in the dorsal and ventral view. Positive b-values indicate that regions are thicker in the PD group compared to controls and negative b-values indicate that regions are thinner. The models are corrected for intracranial volume, age, sex, and cohort. HY Hoehn and Yahr.
