Association between certainty and head circumference. Boxplot showing the distribution of normalized head circumference for each of the ADOS modules. The orange boxes indicate those diagnosed with the highest certainty (15) whereas the blue boxes indicate those diagnosed with a lower certainty (< 15). Normalized head circumference was significantly different between the groups for all three ADOS modules
