Single-Center Experience in Pediatric Lung Transplantation: Clinical Characteristics, Survival, and Post-Transplant Morbidity.
Article in Pediatric transplantation, 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
backgroundPediatric lung transplantation remains a life-saving option for selected children and adolescents with end-stage lung disease. We aimed to describe clinical characteristics, survival, post-transplant morbidity, and exploratory factors associated with mortality in a single-center Saudi cohort.
methodsWe retrospectively reviewed all pediatric patients who underwent lung transplantation between January 2010 and December 2023. Demographic, anthropometric, perioperative, and post-transplant data were extracted. Survival was assessed with Kaplan-Meier analysis, and Cox regression was used to explore associations with mortality.
resultsTwenty-eight recipients underwent transplantation, predominantly bilateral sequential procedures, at a median age of 16 years. All recipients were adolescents, and cystic fibrosis (CF) was the most common indication. Severe undernutrition was common, with 64.3% meeting failure-to-thrive criteria (< 1st centile for weight) and 71.4% below the 3rd centile. Intraoperative extracorporeal membrane oxygenation replaced cardiopulmonary bypass after 2016. One-year survival was 96.4%, and median post-transplant survival was 6.8 years. Survival did not differ significantly by intraoperative extracorporeal support, but median survival was shorter in CF than in non-CF recipients (2.9 vs. 8.9 years). Hypertension developed in 53.5% of patients, diabetes in 28.5%, and acute kidney injury in 46.4%. In age- and sex-adjusted Cox models, CF, longer waiting time, Pseudomonas aeruginosa colonization, and diabetes at 1 year were associated with mortality.
conclusionPediatric lung transplantation in this cohort achieved excellent short-term survival but substantial long-term morbidity. Mortality associations should be interpreted cautiously, given the small sample size and event count. The shorter survival observed in CF recipients warrants further study, particularly in the context of severe undernutrition and chronic airway colonization.
