Figure 1. Summary of the ICHD criteria.

Figure 1

Panel A shows how many ICHD criteria were documented for each headache type. Panel B collapses ICHD criteria into none, partial, and complete, by headache type and visit type. Overall, there was a significant difference (p<0.001) in ICHD documentation based on headache type. Documentation for tension-type headaches was significantly lower than for either type of migraine (p<0.05). There was no statistical difference in the level of documentation by visit type for new versus worsening headaches (p = 0.287).
