You can use a point-and-click web application to generate the main forest plot, funnel plot, as well as a forest plot for each subgroup analysis (dsquintana.shinyapps.io/ot_meta_exec/). The R code to run the application on a local computer is also available on OSF (osf.io/7eg5u/). (5/6)

Interestingly, a subgroup analysis on the subcategories of executive functions showed a small effect on improving cognitive flexibility (g=0.20, P=0.02), which warrants further studies to investigate the effect of oxytocin administration on flexibility. (4/6)

Meta-analyzing 20 effect sizes from 13 studies, we did not find a significant effect of OT on overall executive functions (g=0.07, P=0.3). This result was corroborated by the Robust Bayesian meta-analysis BF=0.1, i.e. moderate support for the absence of an effect for the overall meta-analysis (3/6)

Recent studies have shown that oxytocin is potentially involved in a wider range of functions than previously thought, including learning and memory. To summarize the current literature, we meta-analyzed the effects of oxytocin administration on non-social executive functions. (2/6)
