Representativeness of the GALACTIC-HF Clinical Trial in Patients Having Heart Failure With Reduced Ejection Fraction.
Article in Journal of the American Heart Association, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 Randomized clinical trials in populations with heart failure with reduced ejection fraction may not be reflective of the general population with heart failure with reduced ejection fraction. Our study assessed the representativeness of the GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure) patient population in Kaiser Permanente Southern California. Methods and Results We identified 9770 patients with a diagnosis of heart failure with reduced ejection fraction from 2014 to 2018 using electronic health records. Four mutually exclusive cohorts were created, including GALACTIC-HF-ineligible cohorts: (1) not taking guideline-directed medical therapy (GDMT) and (2) taking GDMT; and GALACTIC-HF-eligible cohorts with: (3) ejection fraction (EF) ≤28% and (4) EF 29% to 35%. Patients were followed for 30-day and 1-year mortality and 30-day, 180-day, and 1-year hospitalization. Overall, 3626 (37.1%) met GALACTIC-HF inclusion criteria with EF ≤35%, and 2367 (65.3%) of those individuals had EF ≤28%. The risk of 1-year mortality was lower among all cohorts versus the GALACTIC-HF-ineligible cohort not taking GDMT (hazard ratio, 0.80 [95% CI, 0.70-0.91], 0.84 [95% CI, 0.72-0.98], and 0.62 [95% CI, 0.51-0.75] for the GALACTIC-HF-ineligible cohort taking GDMT and GALACTIC-HF-eligible cohorts with EF ≤28% and 29%-35%, respectively). Compared with the GALACTIC-HF-ineligible cohort not taking GDMT, the short-term hospitalization risk at 30 and 180 days were similar for both GALACTIC-HF-eligible cohorts and the hospitalization risk at 1 year was similar for the GALACTIC-HF-eligible cohort with EF ≤28%. Conclusions A large portion of patients with heart failure with reduced ejection fraction with low EF met inclusion criteria for the GALACTIC-HF trial and, despite being on GDMT, had hospitalization rates similar to those not taking GDMT, suggesting potential benefits from other innovative treatments.
