RevMan v5.3 and Stata software were used for statistical analysis. Results: A total of 1853 patients with COVID-19 were enrolled in 19 RCTs. Meta-analysis results showed that Integrated Medicine therapy was statistically significant and was associated with improvements in clinical symptoms, including fever disappearance rate [RR = 1.25, 95% CI: (1.04, 1.50), P = 0.02], fatigue disappearance rate [RR = 1.28, 95% CI: (1.00, 1.63), P = 0.05], overall effective rate [RR = 1.17, 95% CI: (1.10, 1.26), P < 0.00001], and chest CT improvement rate [RR = 1.24, 95% CI: (1.14, 1.34), P < 00001], as well as laboratory indicators; for example, CRP [WMD = −4.14, 95% CI: (−6.38, −1.91), P = 0.0003], WBC [WMD = 0.35, 95% CI: (0.11, 0.58), P = 0.004], and LY count [WMD= 0.32, 95% CI: (0.12, 0.52), P = 0.001]. In addition, our imprecise results also showed that Integrated Medicine did not improve the cough disappearance rate [RR = 1.28, 95% CI: (1.00, 1.63), P = 0.05], ESR [WMD = −14.97, 95% CI: (−33.67, 3.72), P = 0.12] and PCT [WMD = −0.01, 95% CI: (−0.03, 0.01), P = 0.16] compared with conventional Western medicine (CWM). Subgroup Analysis showed that the effect of Integrated Medicine is more obvious in improving symptoms when the treatment time is less than 2 weeks. For patients with severe and non-severe COVID-19, Integrated Medicine is more effective in improving fever and cough symptoms than using CWM. Conclusion: The results of the current meta-analysis suggested that the Integrated Medicine can improve the clinical symptoms, chest CT and infection indicators of COVID-19 patients. Even if the treatment time is less than 2 weeks, compared with CWM treatment, the effect of Integrated Medicine in improving symptoms is more obvious. However, the results should be interpreted cautiously due to the heterogeneity among the studies.
