(a) Regression plot of the Childhood Autism Rating Scale, Second Edition based on patient observation (CARS‐2^obs) and Autism Diagnostic Observation Schedule, Second Edition (ADOS‐2) for all patients. (b) Regression plot of the CARS‐2^obs and raw Social Responsiveness Scale, Second Edition (SRS‐2) total scores for all patients. The line of best fit is noted along with the 95% confidence intervals and 95% prediction limits. Although there is evidence of overestimation for a CARS‐2^obs greater than 25, suggesting that the relationship may not be uniformly linear, removal of this group of individuals did not significantly affect the model.
