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
Introduction/background Heart failure (HF) is a prevalent clinical syndrome in Spain, often resulting in hospitalizations and significant morbidity. Guideline-directed medical therapy (GDMT) for HF with reduced ejection fraction (HFrEF) is strongly recommended to reduce mortality and improve cardiac function, yet it remains underutilized at hospital discharge. Structured HF Units (HFUs) may improve adherence to GDMT and optimize patient outcomes. Methods We conducted a retrospective, descriptive, cross-sectional study including 40 consecutive patients with HFrEF discharged from San Juan de Alicante University Hospital and referred to the HFU. At the HFU visit, patients underwent standardized assessments including medical history review, physical examination, New York Heart Association (NYHA) functional class evaluation, medication optimization according to GDMT, laboratory testing as needed, and repeat echocardiography when indicated. All consecutive eligible patients were included; no formal sample size calculation was performed. Quantitative variables were summarized as mean ± standard deviation and range, and qualitative variables as counts and percentages. Changes in left ventricular ejection fraction (LVEF) were analyzed using the Wilcoxon signed-rank test, while associations with age, sex, and GDMT completeness were evaluated using Spearman's correlation and Mann-Whitney U tests (p < 0.05). Results The mean age of the cohort was 68.1 years (range 41-86), with a predominance of male patients (34 (85%)). At discharge, only eight (20%) received full GDMT, but this proportion more than doubled to 21 (52.5%) after follow-up in the HFU. This improvement was accompanied by a significant rise in mean LVEF from 31.5% to 43.0% (mean increase 11.6%, p < 0.001), with a greater gain observed in men. These findings clearly illustrate that the initially low prescription rate of GDMT at hospital discharge was significantly improved after HFU follow-up, and this optimization was associated with better cardiac function. Conclusion GDMT remains frequently underprescribed at hospital discharge, representing a missed opportunity for early optimization. Referral to a structured HFU significantly increases GDMT adherence and improves LVEF, underscoring the critical role of HFUs in multidisciplinary HF care.
