Effect size: utility and application in neuroscience nursing.
Effect size is used in single studies to complement inferential statistical analysis. It also is used to compare and synthesize data across studies in meta-analysis. Effect size provides information about clinical importance of differences found in research observations. For researchers, effect size is useful in establishing support for the theoretical framework of a story and in planning for future research. Application of effect size to data in three studies about the effects of backrest position on ICP and CPP in brain-injured adults illustrates the utility of effect size analysis in neuroscience nursing research.
