As<br \/>\nyou ask yourself, &#8220;Will I get the same results if I use this research?&#8221;, you must address the<br \/>\nprecision of study findings, which is determined by the Confidence Interval. If the CI around the<br \/>\nsample statistic is narrow, you can be confident you will get close to the same results if you<br \/>\nimplement the same research in your practice.\n<\/p>\n<p>Consider the following example. Suppose that you did a systematic review of studies on the<br \/>\neffect of tai chi exercise on sleep quality, and you found that tai chi affected sleep quality in older<br \/>\npeople. If, according to your study, you found the lower boundary of the CI to be .49, the study<br \/>\nstatistic to be 0.87, and the upper boundary to be 1.25, this would mean that each end limit is<br \/>\n0.38 from the sample statistic, which is a relatively narrow CI.\n<\/p>\n<p>(UB + LB)\/2 = Statistic [(1.25 + .49)\/2 = .87]\n<\/p>\n<p>Keep in mind that a mean difference of 0 indicates there is no difference; this CI does not<br \/>\ncontain 0. Therefore, the sample statistic is statistically significant and unlikely to occur by<br \/>\nchance.\n<\/p>\n<p>Because this was a systematic review, and tai chi exercise has been established from the<br \/>\nstudies you assessed as helping people sleep, based on the sample statistics and the CI,<br \/>\nclinicians could now use your study and confidently include tai chi exercises among possible<br \/>\nrecommendations for patients who have difficulty sleeping.\n<\/p>\n<p>Now you can apply your knowledge of CIs to create your own studies and make wise decisions<br \/>\nabout whether to base your patient care on a particular research finding.\n<\/p>\n<p>Initial Post Instructions<\/p>\n<p>Find an example of a confidence interval in the news, scholarly source or medical journal.<br \/>\nSummarize the article\/study.
