Reporting of Basic Statistical Methods in Biomedical Journals: Improved SAMPL Guidelines

Statistical methods have become an essential component of all empirical biomedical research. Science requires that these methods are fully reported with complete accuracy so that the evidence base could be fully appraised for validity, reliability, and generalizability. To meet this objective, Statistical Analyses and Methods in Published Literature (SAMPL) guidelines have been prepared for statistical reporting in biomedical publications. This communication proposes substantial improvement of these guidelines to make them more comprehensive, organized, compact, and easier to adopt.
