title: Regression analysis in medical research.
abstract: Even the most respected medical journals continue to publish articles containing unwarranted conclusions, which thus appear validated. This often results from the unfamiliarity of medical investigators with statistics leading to improper study design, data collection, analysis, and presentation. The increased use of multivariate analysis adds to the perplexity of medical readers not adequately prepared to judge the statistical method. This article attempts to acquaint readers with the terminology of regression analysis and how to use regression formulas.
