Patterns of Adherence and Persistence to Triple and Quadruple Guideline-Directed Medical Therapy Among US Patients With Heart Failure With Reduced Ejection Fraction.
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
backgroundGuideline-directed medical therapy (GDMT) reduces morbidity and mortality in patients with heart failure with reduced ejection fraction (HFrEF) if patients adhere to their prescribed regimen. The objectives of this retrospective observational cohort study were to (1) describe adherence and persistence to triple and quadruple GDMT among patients with HFrEF and (2) identify factors associated with heterogeneity in GDMT discontinuation patterns.
methodsPatients with HFrEF who had ≥2 prescription fills of triple and quadruple GDMT between January 2021 and December 2022 were identified using Optum's deidentified Clinformatics Data Mart. Outcome measures included adherence to triple and quadruple GDMT and the pattern of discontinuation over time. A latent trajectory analysis identified groups of patients with similar patterns of GDMT discontinuation, and characteristics associated with group assignment were evaluated using logistic regression.
resultsOf 107 849 patients with HFrEF, 13 304 (12.3%) received triple GDMT and 2478 (2.3%) received quadruple GDMT; 45.0% and 40.8%, respectively, were adherent to the regimens, whereas 21.0% and 17.5%, respectively, discontinued. Two latent classes of treatment trajectories, labeled early discontinuers and persistent GDMT patients, were identified for both triple and quadruple GDMT. Early discontinuation of therapy was identified in 1393 (10.5%) of patients on triple GDMT and 294 (11.9%) of patients on quadruple GDMT. Patient profiles of discontinuation varied between the cohorts.
conclusionsDespite evidence and guideline recommendations, adherence to triple and quadruple GDMT in patients with HFrEF was suboptimal. Patients with early discontinuation of GDMT had distinct profiles of sociodemographic, clinical, and health care characteristics. These findings suggest that new strategies are needed to improve initiation and adherence to GDMT to optimize clinical outcomes.
