Hey man I am way out of my depth here, but the study really speaks for itself:

> Our analysis population was 8819 adults in the 1999–2004 National Health and Nutrition Examination Survey (NHANES) with reliable data on diet and headache history.

Compare that to Aimovig:

> The 12-week trial, presented this week at the annual meeting of the American Academy of Neurology, involved 246 patients suffering four to 14 migraine headaches a month who had tried two to four preventive treatments that either did not work for them or had intolerable side effects. [0]
