Introducing Critical Care Forum's ongoing review of medical statistics

Statistics is increasingly used in all fields of medicine but is often poorly understood and incorrectly applied. Critical Care is therefore launching a series of articles aimed at providing a simple introduction or refresher to some of the more commonly used statistical tools and ideas. This series does not aim to be an exhaustive review of medical statistics but rather a starting point to inform readers and stimulate more thought and investigation as to the most appropriate statistical methods to use and the theory and assumptions behind them.
