Popis: There is a lack of reporting of effect sizes and confidence intervals in the current biomedical literature. The objective of this paper is to present a discussion of the recent paradigm shift encouraging the use of reporting effect sizes and confidence intervals. Although p-values help to inform us about whether or not an effect exists due to chance, effect sizes inform us about the magnitude of the effect (clinical significance), and confidence intervals inform us about the range of plausible estimates for the general population mean (precision). Reporting of effect sizes and confidence intervals are a necessary addition to the biomedical literature, and these concepts are reviewed in this manuscript.
