Routput_Meta_WithinGroup_ADHD_Neurofeedback_EEG_Meta_Analysis

This file contains the R output from the meta-analysis assessing within-group changes in ADHD symptoms before and after intervention. The analyses compare pre- and post-treatment scores for children and adolescents undergoing portable/wearable EEG-based neurofeedback (NFT) and for those in control conditions. The results summarize effect estimates, heterogeneity tests, and model diagnostics, showing that NFT produced significant symptom improvements within groups, while control groups showed smaller or non-significant changes. These outputs complement the main dataset and support the findings presented in the manuscript and Supplementary Materials.
