Abstract
|
|
|
Objectives :The purpose of this study was to introduce clinicians and researchers to the statistical errors detected in the Journal of Oriental Rehabilitation Medicine (JORM), and to improve the quality of newly-publishing papers in JORM.
Methods :We reviewed 222 articles published in the JORM from January 2005 to October 2009, excluding 74 articles in which statistical analysis was not used. Several statistical errors including an inaccurate post-hoc test, an inappropriate description of statistics program, an improper interpretation of statistical results, an inappropriate use of statistical terminology, and an invalid statistical methodology were investigated using our checklist. Four researchers participated in the statistical evaluation to minimize the biases.
Results :1. Thirteen articles(6%) had an inaccurate post-hoc test. 2. Forty six articles(21%) had the inappropriate or omitted descriptions of statistics program. 3. Sixteen articles(7%) didn`t have full explanation of the statistic method in the body of paper. 4. Twenty two articles(10%) had no description of statistical methods although each of authors mentioned the usage of statistical methods in the body of paper. 5. There were 135 articles(63%) having inappropriate descriptions of the statistical terminology.
Conclusions :Various mistake or misuse of the methodology applications in the articles published in the JORM was found out. A correct application of statistic to the articles and a active participation of the statistical specialists at the beginning of study design were needed to improve the quality of JORM.
