Prevalence and Risk Factors of Readmission Among Patients with Cardiovascular Diseases in Africa: A Systematic Review.
Synthesis in Journal of epidemiology and global health, 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
backgroundCardiovascular diseases (CVDs) are a leading cause of morbidity and mortality globally, with a disproportionately high burden in Africa. Readmissions among patients present an additional challenge. This systematic review aimed to map evidence on the prevalence and risk factors of readmissions among patients with CVDs in Africa.
methodA systematic review was conducted following the PRISMA guidelines. Comprehensive searches were carried out in PubMed Central, Scopus, JSTOR, CINAHL and other databases. Studies published in English from January 2000 that reported on the prevalence and risk factors of readmission among CVD patients in Africa were included. The Joanna Briggs Institute critical appraisal tools were used to assess the quality of included studies. Descriptive and thematic analysis were used to synthesise the findings.
resultsA total of 37 records were included in the final synthesis. Heart failure was the most extensively studied CVD. The prevalence of readmission among patients with CVDs ranged from 1.53% to 67.7%. Older age (> 65 years) was a key predictor. Clinical factors included hypertension, arrhythmias, advanced disease stages including LVEF < 40%, NYHA Class II-IV, NHISS > 7, anemia, infections and chronic comorbidities. Facility-related factors comprised prolonged hospitalisation and discharge without essential medications (beta-blockers for heart failure, and aspirin, clopidogrel, statins for myocardial infarction). Poor adherence to treatment regimen emerged as self-management determinant.
conclusionThe findings suggest that readmissions among patients with CVDs in Africa remain a substantial burden. The review highlights the need for evidence-based interventions focusing on standardised discharge protocols, enhanced patient education, better screening of patients and management of comorbidities. Future research should address geographical gaps and focus on a wider range of CVDs to provide a more comprehensive overview.
