Clinical Researches Evidence Mapping of Traditional Chinese Medicine for Chronic Atrophic Gastritis based on Big Data Platform of Evidence-based Literature of Traditional Chinese Medicine
To systematically analyze the clinical research evidence on traditional Chinese medicine (TCM) in the prevention and treatment of chronic atrophic gastritis (CAG), summarize the efficacy, and provide guidance for future research.
Methods
2
With the help of the big data platform of evidence-based literature of traditional Chinese medicine which covers multiple dominant digestive diseases of TCM, the clinical researches, systematic reviews, guidelines and consensuses on the prevention and treatment of CAG by TCM published between the year 2000 and 2020 were searched for. The publication time, research type, sample size and intervention duration, the distribution of TCM syndromes and constitution in the observational studies, the category and role of prevention and treatment TCM programs (prevention, treatment, rehabilitation/secondary prevention, uncertainty), clinical evaluation indicators and other information of the included articles were statistically analyzed, and the distribution of evidence was presented in the form of both graphics and text.
Results
2
A total of 796 articles were included, involving 775 clinical studies, 19 systematic reviews and 2 expert consensus. Total number of annual publications was slowly moving upward, with highest volume published in 2015 and 2019, both of which were 51. The clinical researches were mainly interventional studies (714 articles), including 518 randomized controlled trials and 196 non-randomized controlled trials; besides, there were 61 observational studies. The sample size in 46.50% (332/714) of the interventional studies was 60~100 cases, and the duration of the intervention in 47.48% (339/714) of the intervention studies was 3~6 months. The intervention explored in the included studies was mainly Chinese herbal medicine. The focused outcome indicators were the total effective rate, endoscopic appearance, histopathology, TCM syndrome scores, clinical symptom improvement, and Hp negative conversion rate, while less attention was paid to the quality of life and psychological evaluation. The methodological quality of systematic reviews was generally low, with the AMSTAR scale scores mainly at 4 to 8 points, and 16 systematic reviews (84.21%) concluded that "evidence shows potential efficacy".
Conclusion
2
TCM has certain advantages in the treatment of CAG, but most evidence have deficiencies in the rationality of research design, the uniformity of diagnostic criteria, and the scientificity of efficacy evaluation. In the future, it is necessary to strengthen the standardization of clinical diagnosis and treatment, and carry out rigorous large sample size, multi-center, randomized controlled trials to improve the evidence of TCM in the prevention and treatment of CAG.
