The concepts and characteristics of comparative effectiveness research (CER) are analyzed to explore its scientific research methodology in clinical efficacy optimization of abdominal acupuncture. The designs of CER focus on patients, which emphasize assessment of comprehensive efficacy in real medical environment instead of simple efficacy in randomized controlled trial (RCT). Its research strategy involves four categories and three subject, covering acquiring, saving and management, comparison and application of clinical evidence, which has practical application value in comprehensive comparison of advantages and efficacy rules of different acupuncture therapies and acupoint prescriptions. By establishing clinical registration system, oversized-sample data could be acquired from different centers to effectively overcome insufficient sample-induced sampling error. It has important value in system summary and optimization of clinical efficacy of abdominal acupuncture. The CER fully illustrates clinical reality of acupuncture-moxibustion and provides strong support of scientific data for optimization of curative effect. It embodies prescription standardization, manipulation normalization and methodization of syndrome differentiation in clinic of abdominal acupuncture, which is expected to achieve evidence-based optimization of treatment prescription and technique in abdominal acupuncture.
