Prevalence of pulmonary hypertension and its associated factors among chronic kidney disease patients in Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia: an institution-based retrospective study.
Article in BMC cardiovascular disorders, 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
backgroundPulmonary hypertension (PH) is associated with significant morbidity and mortality in chronic kidney disease (CKD) patients, including those on dialysis. However, its prevalence in Ethiopia remains unknown. This study aimed to determine the prevalence and associated factors of PH among CKD patients at a tertiary hospital in Ethiopia.
methodsA four-year retrospective cross-sectional study was conducted at Tikur Anbessa Specialized Hospital from September 2020 to September 2024. The study included CKD patients receiving follow-up care at renal and diabetic clinics. Data were extracted from medical records. For the multivariable analysis, all variables with a univariate p-value < 0.20 were entered into the logistic regression model. A p-value < 0.05 was considered statistically significant.
resultsAmong 243 CKD patients (mean age 60.95 ± 12.53 years; 61.7% male), the prevalence of PH was 16.04% (95% CI: 11.8–21.7%), with 6.2% classified as severe. Advanced CKD (stages 3–5) (adjusted odds ratio [AOR]: 3.32, 95% CI: 1.95–11.58, p = 0.048), type 2 diabetes (AOR: 3.18, 95% CI: 1.28–7.89, p = 0.01), and hypertension (AOR: 3.11, 95% CI: 1.35–7.19, p = 0.008) were independent risk factors for PH.
conclusionPH is a significant comorbidity among Ethiopian CKD patients, with modifiable risk factors contributing to its development. These findings underscore the importance of routine PH screening in high-risk CKD populations and context-specific management strategies in resource-limited settings.
