Prognostic significance of dipstick proteinuria in heart failure with preserved ejection fraction: insight from the PURSUIT-HFpEF registry.
Observational study in BMJ open, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThe semiquantitative urine dipstick test is a simple and convenient method that is available in the smallest community-based healthcare clinics. We sought to clarify the prognostic significance of dipstick proteinuria in patients with heart failure (HF) with preserved ejection fraction (HFpEF).
designA PARTICIPANTS AND
settingWe assessed 851 discharged-alive patients in the PURSUIT-HFpEF registry who were initially hospitalised due to an acute decompensated HFpEF (EF≥50%) and elevated N-terminal-pro-brain natriuretic peptide (≥400 ng/L) at Osaka University Hospital and other 30 affiliated hospitals in the Kansai region of Japan. Patients received a urine dipstick test, and were divided into two groups according to the absence or presence of proteinuria. A trace or more of dipstick proteinuria was defined as the presence of proteinuria.
main outcome measuresA composite of cardiac death or HF rehospitalisation.
resultsMedian age was 83 years and 473 patients (55.6%) were female. Five hundred and two patients (59%) were proteinuria (-) and 349 patients (41%) were proteinuria (+). The composite endpoint and HF rehospitalisation occurred more often in proteinuria (+) individuals than proteinuria (-) individuals (log-rank p=0.006 and p=0.007, respectively); but cardiac death did not (log-rank p=0.139). Multivariable Cox regression analysis showed that the presence of proteinuria was associated with the composite endpoint (HR: 1.47, 95% CI 1.07 to 2.01, p=0.016), and HF rehospitalisation (HR: 1.48, 95% CI 1.07 to 2.05, p=0.020), but not with cardiac death (HR: 1.52, 95% CI 0.83 to 2.76, p=0.172).
conclusionsDipstick proteinuria may be a prognostic marker in patients with HFpEF. Evaluation of proteinuria by a urine dipstick test may be a simple but useful method for risk stratification in HFpEF. UMIN-CTR ID: UMIN000021831.
