Mapping a disease specific measure of quality of life to a generic instrument is one available technique to obtain utility values for cost-effectiveness studies. Based on a literature review on mapping techniques in oncology, we found that three models performed best: an OLS (Ordinary Least Square) regression with spline transformation, a multinomial logistic regression and a beta binomial regression. Our objective was to compare those three methods and a standard OLS regression for the mapping of the EORTC QLQ-C30 questionnaire to EQ-5D in patients with non-small cell lung cancer (NSCLC).
