*
Significant at P < 0.05 level. ASD outcome based on 18-, 24- or 36-month ADOS and clinical judgment. Chi-square tests examined associations between participant characteristics and group. t-test examined group difference in age of seizure onset. One TSC/no ASD and one TSC/ASD infant were missing race/ethnicity data. One TSC/no ASD infant was missing maternal education data. One TSC/ASD infant and two TSC/no ASD infants were missing infantile spasm data. One TSC/ASD infant was missing seizure onset data.
