Sample size
n = 722
Population
patients with type 2 diabetes
Methods
A computer search Cochrane, PubMed, Embase, CNKI, Wanfang, VIP, and other Chinese and English databases were conducted for randomized controlled trials of green tea in the treatment of patients with type 2 diabetes. A total of 15 articles were included, encompassing 722 patients. Meta-analysis using Stata15.1 software.

Background

To systematically evaluate the effect of green tea on patients with type 2 diabetes.

Methods

A computer search Cochrane, PubMed, Embase, CNKI, Wanfang, VIP, and other Chinese and English databases were conducted for randomized controlled trials of green tea in the treatment of patients with type 2 diabetes. The duration of these trials spanned from the establishment of the database to January 10, 2024. The obtained data were subjected to meta-analysis using Stata15.1 software. A total of 15 articles were included, encompassing 722 patients.

Results

The meta-analysis results showed that compared to the control group, green tea intervention significantly improved the improvement of fasting blood glucose (SMD = -0.41, 95% CI: -0.67 to -0.19, P = .001), glycated hemoglobin (SMD = -0.68, 95% CI: -1.15 to 0.21, P = .004) and insulin resistance index (SMD = -0.70, 95% CI: -1.18 to -0.22, P = .005) in the experimental group compared to the control group. The differences were statistically significant (P < .05).

Conclusion

Green tea significantly improves fasting blood glucose, glycated hemoglobin and insulin resistance in patients with type 2 diabetes.
