The presentation of results from studies in clinical haematology

Research is based on trying to find answers to specific questions or to test hypotheses. Studies are thus undertaken to generate data which, with appropriate statistical methods, will help to determine the validity of the science under investigation. The aim of this paper is not to provide answers on which statistical methods to use, but will concentrate on suggesting the best ways of presenting the results of appropriately analysed data. And presentation is the key, because however well conducted and analysed a study may be, incorrect or inappropriate presentation of the findings will severely hamper its publication potential. With illustrative examples, the fundamentals required in the presentation of study objectives, population selection, description of characteristics and missing values, survival analyses, unadjusted analyses, multivariate regression models and matched pair analyses, are presented.
