Abbreviations: EORTC-BN20, European Organisation for Research and Treatment of Cancer; GI, gastrointestinal; MDASI-BT, The MD Anderson Symptom Inventory Brain Tumor Module; REM–role functioning, relations with others, enjoyment of life, and mood; QOL, quality of life; WAW, walking, general activity, and work.
Higher scores in the functioning subscale of the EORTC-BN20 denote better outcome. Hence, the negative correlations. All correlations are significant at P less than .005.
