A binomial model was used to compare the empirical detection rates to the expectations in healthy controls32. In patients they were highly significantly larger than in a leave-one-out cross-validation in healthy controls with p-values zero to machine precision. For datasets that did not pass the quality checks we also compared to the detection rate in high quality datasets of TLE patients. In excluded datasets the detection rates were highly significantly elevated.
