Contrast estimates and 90% confidence intervals for disease‐related effects and center/scanner effects (matched groups) Disease‐related effect in the complete data in the (a) left medial frontal gyrus at [−44, 33, 34; x, y, z], (c) left cerebellum [−39, −40, −36], (e) right paracentral lobule [4, −32, 48], (g) right uncus [20, −4, −33], and (J) right precuneus [6, −71, 44]. Differential effects of center/scanner in the (b) left medial frontal gyrus at [−44, 33,34], (d) left cerebellum [−39, −40, −36], (f) right paracentral lobule [4, −32, 48], (h) right uncus [20, −4, −33], and (k) right precuneus [6, −71, 44]. * cluster sizes refer both to the left and right panels; for more details see also Table III.
