Decision tree diagram for the distinguishing of migraine subtypes. In individuals with a headache lasting shorter than 7.2 h, the proportion of MwA in the training set increased to 20.77% from 11.41%. Among them, patients who experienced headaches more than once a month had a 43.64% chance of developing MwA (A). The only variable that ultimately distinguished AWM and AWNM was the duration of headache. In patients with a headache duration shorter than 7.2 h, the proportion of AWNM patients in the training set grew from 40.90–60.30%, while AWNM patients accounted for only 17.10% in patients with a headache duration longer than 7.2 h (B). For distinguishing MwoA from AWNM, the variables were duration of headache, frequency, and whether it was accompanied by nausea. The proportion of AWNM patients in the training set boosted from 6.62–18.58% in patients with headaches lasting less than 7.2 h, while AWNM patients accounted for only 1.93% in patients with headaches lasting more than 7.2 h. If the frequency of headaches was less than 1 day/month, the proportion of AWNM patients increased to 39.64%. There was an 88.62% probability of MwoA in patients with headache duration less than 7.2 h, headache frequency greater than 1 day/month, and accompanied with nausea (C). d/m: days/month
