Reporting of safety results in published reports of randomized controlled trials.

24 Oct 2009 BACKGROUND: Reports of clinical trials usually emphasize efficacy results, especially when results are statistically significant. Poor safety reporting can lead to misinterpretation and inadequate conclusions about the interventions assessed. Our ... Read more...

Designing better graphs by including distributional information and integrating words, numbers, and images.

30 Aug 2009 Statistical graphs are commonly used in scientific publications. Unfortunately, graphs in psychology journals rarely portray distributional information beyond central tendency, and few graphs portray inferential statistics. Moreover, those that do ... Read more...

Design of experiments with multiple independent variables: a resource management perspective on complete and reduced factorial designs.

30 Aug 2009 An investigator who plans to conduct an experiment with multiple independent variables must decide whether to use a complete or reduced factorial design. This article advocates a resource management perspective on making this decision, in which the ... Read more...
