The three columns for each centre shows: the total number of samples (All), the number of unrelated samples (PIHAT < 0.18) (UR) and the ethno-linguistically concordant (EC) samples (self-reported ethno-linguistic identity of a participant is same as the ethno-linguistic identity of at least five of the six parents and grandparents). The column “All” corresponds to the AWI-S1, “UR” corresponds to AWI-S2 and “EC” corresponds to AWI-S3 dataset (Supplementary Table 1).
