When evaluating NDPH against other populations we found NDPH was highest in females above 13 years of age. Most patients remembered the month of headache onset, but very few remembered the exact date. The frequency of onset peaked in February and December, with a post viral association linked during these months. The quality of the pain was more likely to be constant. Sleep issues were more common.
In univariate analyses, prior concussion, sinus issues and dizziness were associated with NDPH. None of the differences were statistically significant. In multivariable analyses, three variables were statistically significantly associated with NDPH. Fatigue (OR: 10.1{4.22-24.0}) was the most important clinical feature while nausea (OR: 0.36{0.17-0.75}) and vomiting (OR: 0.19 {0.07-0.50}) were less likely associated with NDPH.
