Relationship of IgE level in blood among cases and the length of time between diagnosis and blood draw. A. Series 3 patients, no temozolomide treatment. B: Series 3 patients who are on temozolomide therapy. Mean and standard error are shown. Using a general linear model, the trend of IgE was not significantly different among the three categories in no temozolomide treatment, (A, p = 0.15), but significant among the temozolomide-treated (B, p = 0.001).
