a Sulcal-based meta-analysis of intraclass correlation (ICC) for bilaterally averaged sulcal measures (N = 110). Sulcal length showed generally “good” reproducibility, although no regions had ICC > 0.959. Mean depth showed “excellent” reproducibility (ICC > 0.9) for: the inferior frontal sulcus (S.F.inf.) and the superior frontal sulcus (S.F.sup.); sulcal width showed “excellent” reproducibility for: intraparietal sulcus (F.I.P.), superior postcentral intraparietal superior sulcus (F.I.P.Po.C.inf.), central sulcus (S.C.), superior postcentral sulcus (S.Po.C.sup.). Surface area showed “excellent” reproducibility for the central sulcus (S.C.), subcallosal sulcus (S.Call.), and the anterior occipito-temporal lateral sulcus (S.O.T.lat.ant.). b The intraclass correlation (ICC) for left, right, and bilaterally averaged sulcal length, mean depth, width, and surface area across the whole brain is plotted for the four test–retest cohorts. KKI showed the highest ICC across sulci.
