title: Effect size: utility and application in neuroscience nursing.
abstract: 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.
