The second edition, with contributions from leading medical statisticians, has been thoroughly revised and expanded. New chapters include: diagnostic studies; clinical trials and meta analyses; and, confidence intervals and sample sizes.

Featuring methods for using confidence intervals, illustrative worked examples and helpful checklists, this is a truly practical guide for clinical readers to a fundamental aspect of medical statistics.
