Abstract
|
|
|
Objectives: This study aimed to evaluate any clinical research regarding asthma published by the Korean Oriental Medical Society and its sub-societies for future rigorous clinical research.
Methods: Every article relevant to asthma was initially obtained from journals in the Korean Oriental Medical Society and its sub-societies by electronic search at journal web sites or manual search. Journals were limited to those registered by the Korea Research Foundation. From initial findings, two independent reviewers selected clinical articles and these articles were further analyzed separately into predefined criteria according to prospective and retrospective studies. For prospective studies, quality assessment was also conducted.
Results: From 99 articles initially obtained, 19 were finally analyzed. 14 were prospective whereas 5 were retrospective. Among the prospective articles, there were no randomized controlled trials and the non-randomized studies had no control groups, with several problems of quality regarding pre-calculated study size and unbiased assessment. None of the retrospective studies described asthma diagnosis objectively and outcome measures were either non-relevant to asthma or non-validated.
Conclusions: Well-designed randomized controlled studies for asthma are needed and more rigorous non-randomized controlled studies should be conducted.
