“No significant change was observed in HDL-C concentrations in healthy participants or in subjects with coronary artery disease supplemented with black tea based on both fixed-effects and random-effects analysis when compared with control participants.”
- Population
- Healthy participants and, separately, subjects with coronary artery disease in pooled randomised trials
“As shown in, the consumption of black tea did not significantly lower TC concentrations in healthy subjects based on both fixed-effects analysis (−3.76 mg/dL; 95% CI, −7.67 to 0.16 mg/dL; P = 0.06) and random-effects analysis (−2.85 mg/dL; 95% CI, −8.02 to 2.31 mg/dL; P = 0.28).”
