Habitual coffee consumption and risk of incident heart failure: an updated systematic review and dose-response meta-analysis of prospective cohort studies.
Synthesis in Journal of health, population, and nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCoffee is among the most widely consumed beverages globally, yet evidence specifically examining its association with heart failure (HF) risk remains limited. The only dedicated meta-analysis on this topic was published in 2012. We conducted an updated systematic review and dose-response meta-analysis to comprehensively evaluate the association between coffee consumption and incident HF.
methodsWe searched PubMed, Embase and Scopus from January 2012 through October 2025 to update the original meta-analysis. Prospective cohort studies reporting hazard ratios for coffee consumption and incident HF were included. Random-effects models were used to pool estimates. Subgroup analyses were planned to examine effects by sex, geographic region, coffee type, and population characteristics where possible. Certainty of evidence was assessed using GRADE.
resultsThirteen studies comprising 656,666 participants and 20,646 HF events were identified. Pooled analysis of 7 independent cohorts demonstrated that moderate coffee consumption (2-4 cups/day) was associated with significantly reduced HF risk (HR 0.925; 95% CI 0.882-0.971; P = 0.002) with negligible heterogeneity (I²=0%). A J-shaped dose-response pattern was suggested, although the test for non-linearity was borderline significant (P = 0.066), with maximal benefit observed at 1-2 cups/day. Within-cohort analyses indicated similar associations for caffeinated and decaffeinated coffee. No evidence of publication bias was detected (Egger's P = 0.99). Certainty of evidence was rated as low.
conclusionsThis updated meta-analysis suggests moderate coffee consumption is linked to lower incident heart failure risk, though certainty is low. Associations observed within-cohort analyses were similar for caffeinated and decaffeinated coffee, indicating moderate intake may be compatible within heart-healthy dietary patterns.
