Raw scores for each variable are reported; all cognitive measures are corrected for gender, age, education; all the analyses were covaried by nonautistic symptoms severity (PANSS–PAUSS). Post-hoc comparisons include Bonferroni correction.

Abbreviations: Aut-S, autistic schizophrenia; Moderate, moderate ASD symptoms; Non-Aut-S, nonautistic schizophrenia.
