  • Xie et al undertook a systematic review and meta-analysis of coffee consumption and risk of hypertension:
    • risk of hypertension was reduced by 2% (relative risk (RR) = 0.98, 95% confidence interval (CI) 0.98-0.99) with each one cup/day increment of coffee consumption
    • provides quantitative evidence that consumption of coffee was inversely associated with the risk of hypertension in a dose-response manner
    • RRs of hypertension risk were 0.97 (95% CI 0.95-0.99), 0.95 (95% CI 0.91-0.99), 0.92 (95% CI 0.87-0.98), and 0.90 (95% CI 0.83-0.97) for 2, 4, 6, and 8 cups/day, respectively, compared with individuals with no coffee intakes
