Table 1 The relationship between the atmospheric pressure and migraine incidence

  1. MA migraine with aura, MOA migraine without aura, TTH tension-type headache, ns not significant
  2. Patients developed migraine at a rate of 23.5 % when the atmospheric pressure ranged from 1005 to <1007 hPa, and at a rate of 26.5 % when the atmospheric pressure ranged from 1003 to <1005 hPa. These proportions were significantly larger than those in case of controls (both p values were <0.05)
