Idiopathic intracranial hypertension incidence and obesity rates in Minnesota

In this correlation between age-adjusted idiopathic intracranial hypertension (IIH) incidence and obesity rates in Minnesota (R² = 0.70, P = 0.008), each point represents two-year intervals. The obesity rates increased consistently throughout the time period of the study and corresponded to an increase in the incidence of IIH. Graph reprinted with permission from Ophthalmology.
