  1. The table presents the results of applying version 3 of the classification criteria for individual headache attacks on the 133 headache attacks experienced by the 18 patients that have successfully participated in the first and second data collection wave of the mBrain study, split up based on the diagnosis of the participating patients. Columns entitled W1 and W2 present the results for wave 1 and wave 2, respectively. Patients with mostly diagnosis classifications are patients for who the patient’s diagnosis matches the disorder type for which there are the most classifications out of the patient’s headache attacks. Abbreviations used in this table: classif. is classifications, CH is cluster headache, TTH is tension-type headache, pct. is percentage, SD is standard deviation, “#” represents “number of”
