Abstract

|
|
Objectives: Since The Journal of Korean Acupuncture and Moxibustion Society(JKAMS) started publishing in 1984, randomised controlled trials(RCTs) and non-randomised clinical studies(NRSs) consist- ently have increased in quality and quantity. There has been no study on quality assessment of NRSs. Thus, this study evaluted non-randomised comparative clinical trials in the JKAMS to assess the quantity and quality.
Methods: Upon extracting NRSs for assessing the intervention effects from all the articles published in the JKAMS from 1984 to 2009, assessments were made on methodological index for non-randomised studies(MINORS). Also, the analysis were made upon the proportion of non-randomised comparative clinical trials within original articles. The mean scores by research methods and years, and total scores and mean scores of yearly research methods were analyzed.
Results: A total of 44 trials on non-randomised comparative clinical trials were selected. In 1980s, 4.3% of the total selected original articles, in 1990s, 4.1%, and in 2000s 14.2% were NRSs. According to the research designs, the mean scores of MINORS were Case-control study 18.3, Controlled before and after 18.5, Quasi randomised trial 18.5, and non randomised trial 17.9(out of 24), respectively. Cross-sectional study was the most frequently used(41.9%).
Conclusion: Although NRSs consistently increased in quantity, the assessed mean scores were low and most articles used Cross-sectional study. Thus, there should be studied using appropriate research methods in the future.
