The aim of this study was to systematically review studies reporting language outcomes in individuals with autism spectrum disorder.MethodA comprehensive search strategy with a well-established sensitive prognosis filter for Medline, adapted for five other databases, was used. Included studies observed individuals diagnosed with autism spectrum disorder for ≥12 months and had ≥30 participants.
