Abstract
Setting the sample size for health intervention trials typically requires interaction between statisticians and health professionals. In this talk I will bring together some of the methods for sample size calculation to show how the core formulae can help the statistician to improve the inputs and outputs. The second part of the talk consists of an introduction to biomarkers and appropriate late phase designs for their evaluation, with a worked example to set the sample size of a two-stage early-phase biomarker study with local health professionals.
Series This talk is part of the MRC Biostatistics Unit Seminars series.
