Variables recorded in the clinic questionnaire.

Distribution of Primary Headaches by ICHD type in this study sample (n = 255)1.
Table 3.
Clinical characteristics of Migraine (ICHD 1.x) patients (n = 206).
Figure 1.
Age at onset of migraine headache (in years) compared across gender:
No significant difference is seen.
Figure 2.
Median reported age at onset and age at first presentation in migraine patients (in years) across family history of disease:
Onset and presentation of migraine is significantly earlier in patients with first-degree family history of headache as compared to patients with no such history (p = 0.003 and p<0.001 respectively).
Table 4.
Co-morbidity in patients with migraine headaches (ICHD 1.x, n = 206).
Figure 3.
Reported age at onset (in years) of migraine and tension-type headache:
Migraine onset peaks in the second and third decade of life and falls later on unlike tension-type headache.
Figure 4.
Frequency of headache episodes in migraine and tension-type headache:
In contrast with migraine, majority of the patients with tension-type headache suffered from headache on more than 14 days per month. The frequency of headache episodes in patients with tension-type headache was higher than those with migraine (p<0.001).
