Demographics and percentage of NF1 patients affected by non-optic glioma per age group. a Number of male and female NF1 patients per age group.

Individuals may appear in more than one age group if scanned in more than one age range. b The overall prevalence of non-optic glioma appears stable in adulthood. Each person is counted once per age group, regardless of number of scans in that age group. Individuals may appear in more than one age group if scanned in more than one age range. Error bars are 1.96 standard deviations of a Poisson distribution
