Plotting mean scores on the primary outcome measure (Social Responsiveness Scale-2) separately for younger and older children.
Error bars represent 95% confidence intervals.To further break down this interaction, we used individual repeated measures ANOVAs to look at differences between visits (V1 and V3, V1 and V4) between the oxytocin and placebo conditions separately for each age group. Considering first the 3–5 year age group, there was a significant difference in SRS-2 total scores from V1 to V3; such that participants in the oxytocin condition demonstrated a larger change in scores from baseline to post-treatment (indicating improvement) relative to those in the placebo condition,
