Oxytocin treatment for core symptoms in children with autism spectrum disorder: a systematic review and meta-analysis
ConclusionWhile the therapeutic value of oxytocin in treating core symptoms of ASD in children is not fully established, the results of this meta-analysis indicate a potential moderate effect. However, further studies with larger sample sizes and more robust RCTs are needed to directly demonstrate the efficacy of oxytocin. Future research should also focus on effect size and outcome evaluation accuracy while minimizing bias in RCT experiments.
