Table 1: Serum glucose concentrations in OGTT (mean values and standard deviations) in particular groups. IA- group of patients treated surgically for tumors of hypothalamic-pituitary area; IB - group of patients treated with surgery and radiotherapy for tumors of hypothalamicpituitary area; IIA –group of patients treated with surgery, chemo- and radiotherapy for tumors outside the h-p area; IIB – group of patients treated surgically for tumors outside the h-p area; IIC- patients with optic nerve glioma treated with chemotherapy. Analysis was made by Fisher test. Values marked by “*” were calculated by U Mann-Whitney test. Statistically important differences were marked as bold.
