Meta-Analysis
Does chronic coffee consumption affect blood pressure or the development of hypertension?
Relative Risk: 1.03 (95% CI 0.98–1.08)
Low-quality evidence suggests that chronic coffee consumption does not have a statistically significant effect on blood pressure or the risk of developing hypertension.
Steffen et al. (2012) conducted a meta-analysis in Hypertension. Coffee consumption vs. Less or no coffee was evaluated on Developing hypertension (RR 1.03, 95% CI 0.98-1.08). Chronic coffee consumption did not significantly affect blood pressure or the risk of developing hypertension (RR 1.03; 95% CI 0.98-1.08).
