Comment on "The effect of preoperative chest physiotherapy on oxygenation and lung function in cardiac surgery patients: a randomized controlled study".
ANN SAUDI MED 2022 JULY-AUGUST WWW.ANNSAUDIMED.NET 288 We read the article titled “The effect of preoperative chest physiotherapy on oxygenation and lung function in cardiac surgery patients: a randomized controlled study” published in your journal.1 I would like to commend the authors for evaluating the effect of preoperative chest physiotherapy in 100 patients undergoing cardiac surgery. The article is plausible and complete in every aspect, however, there are a few other statistical tests and crucial reporting items missing. First, about the statistical test, it would be better to compare the mean difference between the two groups or use ANCOVA with baseline measurements as covariant.2,3 By doing so, authors will be able to provide robust evidence to use preoperative physical therapy modalities in patients undergoing cardiac surgery.4 Second, authors need to report the effect size for readers to evaluate the magnitude of the experimental effect.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
