Histograms of prediction scores (x-axis) compared to clinician-assigned surveillance case definition (blue: autism spectrum disorder (ASD), red: non-ASD).
Horizontal bar represents classification score threshold. Upper panel: classifications for 2008 (training) data. Bottom panel: 2010 (test) data, discordant classifications are highlighted in a lighter shade of blue or red.
