Study Design

Type
Meta-Analysis
Population
subjects older than 18 years of age with hypercholesterolemia
Methods
Systematic review with meta-analysis of randomized clinical trials (RCTs)

Aim

To determine if the black tea is more effective in serum lipid profile that placebo in subjects with hypercholesterolemia.

Design

Systematic review with meta-analysis of randomized clinical trials (RCTs).

Data sources

The databases Medline, Central, Embase, Lilacs, Cinahl, SPORTDiscus, and Web of Science were searched from inception up to January 2019.

Eligibility criteria for selecting studies

RCTs that compared black tea versus placebo, that included serum lipid profile outcomes in subjects older than 18 years of age with hypercholesterolemia.

Results

Seven RCTs met the eligibility criteria, and for the quantitative synthesis, six studies were included. Mean difference for total cholesterol was 1.67 mg/dl 95% CI = -5.47 to 8.80 (p = 0.65), mean difference 0.28 mg/dl, 95% CI = -3.89 to 4.45 (p = 0.90) for triglycerides, mean difference 3.21 mg/dl, 95% CI = -11.02 to 4.60 (p = 0.42) for low density lipoprotein-cholesterol, mean difference 0.38 mg/dl, 95% CI = -1.12 to 1.87 (p = 0.62) for high density lipoprotein-cholesterol.

Conclusion

In the short term, no significant differences were found in lipid serum profile comparing black tea consumption with placebo.
