Cohort Study of Initial Diuretic Dosing and Outcomes Among Patients Hospitalized for Congestive Heart Failure: Insights From the Cardiovascular Quality Improvement and Care Innovation Consortium.
Observational study in Journal of the American Heart Association, 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
backgroundLittle is known about the initial dosing of loop diuretics among patients hospitalized for heart failure and its association with outcomes.
methodsWe identified patients admitted for heart failure at 24 hospitals across two health systems between January 1, 2017, and December 31, 2020. Initial diuretic dose was categorized relative to home dose in furosemide equivalents. The primary outcomes (length of stay) and secondary outcomes (rates of acute kidney injury, in-hospital mortality, and 30-day readmissions) were compared across categories of initial diuretic dose.
resultsAmong 14 332 patients admitted for heart failure, the initial diuretic dose was lower-than-home dose in 1866 (13.0%) patients, equivalent-to-home dose in 3171 (22.1%) patients, and higher-than-home dose in 9295 (64.9%) patients. Compared with patients who received an equivalent or higher initial diuretic dose relative to home dose, risk-adjusted length of stay was longer among patients receiving a lower dose (4.9 days versus 4.0 days versus 4.0 days,
conclusionsIn a cohort of patients admitted for heart failure, more than 1 in 3 patients received an initial dose of intravenous loop diuretics that was lower than or equivalent to their home diuretic dose, and the initial dose was associated with length of hospital stay and acute kidney injury.
