1 · What the graph read from it

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.

2 · The registry

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

aimsTo assess the relationship between coffee consumption and all-cause mortality in heart failure (HF) patients, using data from the National Health and Nutrition Examination Survey (NHANES). METHODS AND

resultsWe analyzed data from NHANES (2003-2018), including 915 participants with HF who reported daily caffeine intake. Participants were categorized into coffee consumption levels: zero, one, two, three, and ≥4 cups/day. Multivariate logistic regression evaluated the relationship between coffee intake and mortality, adjusted for age, sex, and income. The mean participant age was 67, with 401 (44%) women. While one to three cups/day showed no significant association with mortality, consuming ≥4 cups/day increased mortality risk (OR: 1.58; 95% CI: 1.16-2.16; p=0.004). Age was the strongest predictor of mortality, while income and sex showed marginal associations.

conclusionsConsuming up to three cups of coffee per day may be safe for patients with HF, while intake of four or more cups warrants caution due to the association with increased mortality. These findings underscore the need for further research to provide reliable recommendations.
