Transparency in the conduct and reporting of clinical trials is supported by the guidance produced on the content of clinical trial protocols and reporting standards for clinical trials. While the principle features of the statistical analysis are required within this guidance it is generally accepted that a separate Statistical Analysis Plan is also developed as the level of detail appropriate for a SAP is excessive for a protocol. However, there is no detailed guidance on the content of a SAP and consequently, there is marked variation in practice.
Abstract Importance While guidance on statistical principles for clinical trials exists, there is an absence of guidance covering the required content of statistical analysis plans (SAPs) to support transparency and reproducibility. Objective To develop recommendations for a minimum set of items that should be addressed in SAPs for clinical trials, developed with input from statisticians, previous guideline authors, journal editors, regulators, and funders.
Many of the scandals that surround modern medicine involve research conducted on human subjects. Consequently when discussion turns to the ethics of research, such atrocities as the Nazi hypothermia experiments at Dachau conentration camp during World War Two (Berger 1990) or the Tuskegee Syphilis Study in Alabama beginning in the 1930s (Pence 2000) are never far from the surface...The reaction to these atrocities has, justifiably, been extreme. In this paper, Sheehan considers the consequences of these reactions - the exclusion of particular groups from participation in research.
