Cortical thickness alterations in ASD and ADHD. The SDM software uses the peak coordinates and effect sizes of clusters showing significant difference between patients and controls to create an effect-size signed map and its variance map for each study. Then random-effects analysis was performed to obtain the mean map of included studies, weighted by sample size, the variance of each study, and between-study heterogeneity. The boundary of the result clusters in the mean map was determined by corresponding statistical thresholds. Subsequently, the results maps of ASD vs controls, ADHD vs controls, and the comparison between ASD and ADHD were mapped onto the Colin 27 brain template to generate Fig. 2
