ADOS classification based on mean calibrated severity scores of each calibration cell. Scores from Dutch sample with scores from Gotham’s sample in parentheses. ADOS Classification in Dutch sample, when different from Gotham’s sample: ADOS classification in Gotham’s sample in parentheses. * = scores significantly lower in the Dutch sample compared to the sample of Gotham et al. (2009), based on 95% Confidence Intervals. For cells 10 and 16, no Dutch data are available
