Two-way repeated measures ANOVA of headache and dizziness scores for comparisons between groups and time points. Error bars represent the SD. VM, vestibular migraine; HIT-6, Headache Impact Test; DHI, Dizziness Handicap Inventory. HIT-6—main effect of time: F = 22.43, p < 0.0001; main effect of group: F = 212.24, p < 0.0001; interaction: F = 23.09, p < 0.0001. Post hoc test: VM and tension-type headache groups > non-headache group at time 1–3; time 1 > time 2 and 3 in the VM and tension-type headache groups; time 1 < time 2 and 3 in the non-headache group. Frequency of headache—main effect of time: F = 14.40, p < 0.0001; main effect of group: F = 71.77, p < 0.0001; interaction: F = 7.94, p < 0.0001. Post hoc test: VM and tension-type headache groups > non-headache group at time 1–3; time 1 > 3 in VM group; time 1 > 2 and 3 in the tension-type headache group. DHI—main effect of time: F = 164.46, p < 0.0001; main effect of group: F = 17.37, p < 0.0001; interaction: F = 3.68, p = 0.01. Post hoc test: VM and tension-type headache groups > non-headache group at time 1; tension-type headache group > non-headache group at time 2–3; time 1 > 2 and 3 in the VM group; time 1 > 2 > 3 in the tension-type headache and non-headache groups.
