This supplement contains the results from studies in the eight countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Each collaborating centre has assessed the relative validity and reproducibility of the dietary assessment method being used in their centre. One study has also looked at the relative validity of a measure of physical activity, and another study presents the results on an inter-observer study of anthropometric measures. The paper by Kaaks 1 discusses some fundamental assumptions (particularly the statistical independence of random measurement errors between different measurements) that govern the design and analysis of the preliminary validity studies of the pilot phase of the EPIC project. He presents the rationale for conducting additional ‘calibration’ studies on representative subsamples of participants in the main cohort studies, and the way the results from the calibration study in each centre may be used to allow the data to be pooled and used to explore the relationship between a wider range of intake and cancer risk. The paper by Kaaks, Slimani and Riboli 2 gives an overview and summary of the
