Abstract

OBJECTIVE:

By analysing the defect of control design in randomized controlled trials (RCTs) of simple obesity treated with acupuncture and using acupuncture as the contrast, presenting the essential factors which should be taken into account as designing the control of clinical trial to further improve the clinical research.

METHODS:

Setting RCTs of acupuncture treating simple obesity as a example, we searched RCTs of acupuncture treating simple obesity with acupuncture control. According to the characteristics of acupuncture therapy, this research sorted and analysed the control approach of intervention from aspects of acupoint selection, the penetration of needle, the depth of insertion, etc, then calculated the amount of difference factor between the two groups and analyzed the rationality.

RESULTS:

In 15 RCTs meeting the inclusion criterias, 7 published in English, 8 in Chinese, the amount of difference factors between two groups greater than 1 was 6 (40%), 4 published in English abroad, 2 in Chinese, while only 1 was 9 (60%), 3 published in English, 6 in Chinese.

CONCLUSION:

Control design of acupuncture in some clinical RCTs is unreasonable for not considering the amount of difference factors between the two groups.

KEYWORDS:
