Natriuretic response prediction equation for use with oral diuretics in heart failure.
Article in European heart journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND AND
aimsLimited data are available to assess oral diuretic response in outpatients with heart failure (HF). The natriuretic response prediction equation (NRPE) predicts natriuresis following a loop diuretic dose using a urine sample 2 h after the dose and was validated to accurately predict intravenous diuretic response. The primary aim was to validate the NRPE's assessment of oral diuretic response in patients with HF.
methodsThe NRPE was evaluated in two HF patient cohorts receiving oral loop diuretics: Mechanisms of Diuretic Resistance (MDR) and TRANSFORM-Mechanism. Participants received their home oral loop diuretic followed by a supervised timed urine collection including spot urine samples at 1 and 2 h. Patients quantified their self-assessed diuretic response (urine volume) via a standardized survey. A poor diuretic response was defined as cumulative natriuresis < 50 mmol over the study visit.
resultsThe MDR cohort included 318 oral diuretic administrations from 237 patients. The NRPE predicted a poor natriuretic response with an area under the curve (AUC) of .87 [95% confidence interval (CI) .83-.91] and similar accuracy to the previously validated intravenous NRPE performance (P = .16). Patient's ability to self-estimate their diuretic response was poor with an AUC of .57 (95% CI .44-.70) and significantly worse than the oral NRPE (P < .001). In TRANSFORM-Mechanism (110 oral diuretic administrations), the NRPE had similar operating characteristics (AUC .89, 95% CI .80-1.0) for poor diuretic response.
conclusionsNatriuretic response to an oral diuretic can be rapidly and accurately assessed with a urine sample collected 2 h after an oral diuretic dose and the NRPE.
