  1. These results are the output of applying the different versions of the classification criteria for individual headache attacks on the headache attacks experienced by the 4 CH patients that have successfully participated in the first and second wave of the mBrain study (2 in wave 1, 2 in wave 2). Columns entitled W1 and W2 present the results for wave 1 and wave 2, respectively. The numbers in the cells represent the number of attacks that are classified as the type specified in the row header, out of the total number of attacks registered by CH patients during that wave (i.e., 20 attacks for wave 1, 15 attacks for wave 2); the percentages of these ratios are given between brackets. Abbreviations used in this table: CH is cluster headache, TTH is tension-type headache
