MtDNA copy number in autism with and without family training compared with controls. One-way analysis of variance (ANOVA) of the mean values was used to analyze the difference of mtDNA copy number among groups (F=6.042, P = 0.003) and the LSD test was used for multiple comparisons between any of the two groups. The differences of mtDNA copy number betweencontrol group and autism subgroup without family training, and autism subgroup withfamily trainingwere statistically significant (P = 0.002, 0.024, respectively). There is no significant difference in mtDNA copy number between patients with and without family training(p=0.592).
