showed a trendP = 0.010
Including the TD group in the analysis (i.e., analyzing all children together) resulted in a similar result, except that the RRB scale now showed a trend in the same direction (ADI-R total n = 175, r = 0.193, P = 0.010; ADOS CS n = 179, r = 0.216, P = 0.004; ADOS SA CS n = 179, r = 0.230, P = 0.002; ADOS RRB n = 179, r = 0.140, P = 0.062; Supplementary Fig. 3 ).
