  1. Abbreviations: CI=confidence interval; IGF=insulin-like growth factor. The ‘Model/P-value’ indicates the overall level of significance of the multivariate model. With the exception of ‘Age’, which is a quantitative variable, all of the others are binary. Resection distinguishes between partial and complete, adjuvant treatment between radiotherapy and radiotherapy+temozolomide and IGF-IR between positive (LI⩾1%) and negative (LI<1%). The individual P-values represent the levels of significance of the independent contributions of each factor.
