G-coefficients and D-coefficients (Shavelson and Webb, 1991) providing estimates of relative and absolute measurement reliability, respectively, for a multisite study design in which each subject is studied on one occasion on a scanner drawn randomly from the set of all available scanners, as well as average within-site (test-retest) intraclass correlations in left and right hemisphere anterior cingulate cortex (ACC), dorsolateral prefrontal cortex (DLPFC), supplementary motor cortex (SM), insula (IN), inferior temporal cortex (IT), superior parietal cortex (SP), occipital cortex (OCC), thalamus (T), basal ganglia (BG), and cerebellum (C) for the correct trials versus rest contrast, and for medial frontal gyrus (MFG) and posterior cingulate cortex (PCC) for the rest versus correct trials contrast. Figures in parentheses represent 95% confidence intervals (Zhou et al., 2011).
