Associations between total intracranial volume and clinical measures in the two subtypes. A Total intracranial volume is correlated with performance IQ in Subtype 1 (r = 0.239 and p = 0.027); B Total intracranial volume is correlated with ADOS communication score in Subtype 2 (r = 0.233 and p = 0.047); C Total intracranial volume is correlated with ADOS social score in Subtype 2 (r = 0.236 and p = 0.045)
