Time to first cardiovascular hospitalization after guideline-based treatment optimization: A multicenter retrospective cohort study in northwest Ethiopia.
Article in International journal of cardiology. Cardiovascular risk and prevention, 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
Background: Cardiovascular hospitalization is a leading cause of morbidity and mortality, especially in low-resource settings. Evidence on predictors in Ethiopia is limited, hindering targeted interventions. Objective: To assess the incidence and predictors of first cardiovascular hospitalization within one year of treatment optimization in Northwest Ethiopia. Methods: A retrospective cohort study was conducted at three tertiary hospitals. Baseline demographic, clinical, and treatment data were extracted from medical records of patients receiving optimized cardiovascular therapy. Multivariate Cox proportional hazards regression with robust standard errors identified independent predictors of first hospitalization. Results: Among 470 patients, 218 (46.4%) were hospitalized within 12 months; median time to first admission was 100 days (IQR 55-160). Independent predictors of shorter hospitalization-free survival included partial or no guideline-directed medical therapy (HR 1.71, 95% CI: 1.30-2.25), Charlson Comorbidity Index ≥3 (HR 1.62, 95% CI: 1.25-2.10), heart failure with reduced ejection fraction (HR 1.46, 95% CI: 1.10-1.94), chronic kidney disease (HR 1.41, 95% CI: 1.02-1.95), current smoking (HR 1.40, 95% CI: 1.01-1.95), low physical activity (HR 1.35, 95% CI: 1.03-1.77), age ≥65 years (HR 1.36, 95% CI: 1.05-1.76), and absence of a scheduled follow-up plan (HR 1.60, 95% CI: 1.18-2.16). Conclusions: Nearly half of patients experienced hospitalization within one year, mostly within 3-4 months. Ensuring guideline-directed therapy, structured follow-up, and addressing modifiable risk factors may reduce early cardiovascular admissions in low-resource settings.
