Fig. 2: Main voxel-based SPM analysis comparing each of the baseline cholinergic subgroups against control participants with independent samples t tests.
From: A multicenter longitudinal study of cholinergic subgroups in Parkinson disease
Statistical t-contrast images were thresholded with false discovery rate (FDR) threshold of P < 0.05. Positive contrast values (red color scale) indicate statistically significant upregulation of [18F]FEOBV uptake in subgroups relative to control subjects, with negative values indicating statistically significant deficits (blue color scale).
