Abstract

Objectives: This study aimed to evaluate the efficacy and safety of Bojungikgi-tang (BJIG) and its modifications for patients with anemia. Methods: The subject of analysis of this study was a parallel design randomized controlled trial in which BJIG or its modifications was administered orally to patients who met the World Health Organization's anemia criteria and the efficacy and safety were prospectively measured. Electronic databases were searched to retrieve eligible literature published from 1 January 2000 to 12 February 2023. A meta-analysis was conducted, and the risk of bias (RoB) and level of evidence of the included studies was assessed using the Cochrane RoB 2 tool and GRADE method, respectively. Results: Five studies were included in the meta-analysis. When BJIG or its modifications was administered to anemia patients receiving conventional treatment, additional benefits compared to the non-administered group were found in terms of an increase in red blood cell count (mean difference (MD) 0.46 × 1012/L, 95% confidence interval (CI) 0.17 to 0.74), hemoglobin concentration (MD 9.28 g/L, 95% CI 6.06 to 12.51), hematocrit (MD 2.57%, 95% CI 1.76 to 3.38), total effective rate (odds ratio 5.29, 95% CI 2.05 to 13.68), and traditional Chinese medicine symptom scores (standardized MD -1.51, 95% CI -2.79 to -0.24). Conclusions: This study demonstrated the clinical potential of BJIG and its modifications to provide additional benefits to patients with anemia receiving conventional treatment.
