The 3 totals given for the test set are (1) the total across the test set participants with seizures recorded (N=2), (2) the total when including all patients with epilepsy recruited at the London site with data recorded (not listed, N=31), and (3) the total when excluding 1 participant with an artificially disproportionate number of false positives (N=30).
