Abstract There has been ongoing research on the ratio of theta to beta power (Theta/Beta Ratio, TBR) as an EEG-based test in diagnosis ADHD. Earlier studies reported significant TBR differences between patients with ADHD and controls. However, a recent meta-analysis revealed marked decline effect size for difference controls published past decade. Here, we if EEG processing explain heterogeneity findings. We analyzed data from two multi-center clinical studies. Five different signal algorithms were applied calculate TBR. Differences resulting TBRs subsequently assessed usability iSPOT-A dataset. Although there TBRs, none distinguished children without ADHD, no consistent associations symptoms arose. Different methods result significantly TBRs. healthy our sample. The secular is most likely explained by factors other than processing, e.g. fewer hours sleep participants inclusion criteria
