Characterizing a Clinical Trial - Representative, Real-World Population with Heart Failure with Reduced Ejection Fraction.
Article in Clinical epidemiology, 2022. 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
purposeGiven known differences between real-world and clinical trial populations, we characterized demographics, clinical characteristics, and outcomes using real-world (RW) data for patients with heart failure with reduced ejection fraction (HFrEF), including those similar to subjects enrolled in an HFrEF clinical trial to better understand patient populations that could benefit from novel therapies. PATIENTS AND
methodsUsing Vanderbilt University Medical Center electronic health records (2006-2019), two RW cohorts of HFrEF patients were identified. The "Clinical Cohort" was based on a validated HFrEF algorithm and left ventricular ejection fraction (LVEF) ≤40%. The "GALACTIC-HF-like Cohort" mirrored enrollment requirements of the GALACTIC-HF clinical trial including hospitalizations, medications, laboratory values, and LVEF ≤35%.
resultsMedian age at index for the Clinical Cohort (N = 3954) and GALACTIC-HF-like Cohort (N = 1541) were 65 and 61 years, respectively; both were 67% male and 80% white. Over half had coronary artery disease (55% Clinical vs 64% GALACTIC-HF-like); hypercholesterolemia was common (69% Clinical vs 74% GALACTIC-HF-like). Chronic kidney disease (31 vs 21%), atrial fibrillation (32 vs 29%), and cardiac resynchronization or implantable cardioverter defibrillator (26 vs 23%) were higher in the GALACTIC-HF-like Cohort. ACE inhibitor use was high in both groups but more common in the GALACTIC-HF-like Cohort (71% and 82%, respectively). Beta-blockers or loop diuretics were used by >90% of both cohorts. HF hospitalization rates were 261 (95% CI 224, 297) per 1000 person-years in Clinical versus 523 (484, 562) in GALACTIC-HF-like Cohort (median follow-up of 2.9 and 4.2 years, respectively).
conclusionApproximately 40% of RW HFrEF patients met criteria for the GALACTIC-HF trial. While findings of ongoing clinical trials may be directly generalizable to this sizable proportion of patients, future trials should examine whether the majority of patients with lower prevalence of comorbidities and rate of HF hospitalization could benefit from emerging HF treatments.
