Association between immunologic risk factors and cardiovascular complications following pediatric kidney transplantation.

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
backgroundChildren with chronic kidney disease (CKD) are at markedly increased risk for cardiovascular morbidity beginning early in life. While cardiovascular risk factors have been extensively studied in adult kidney transplant recipients, contemporary data in pediatric kidney transplant recipients (PKTR) remain limited, particularly regarding post-transplant cardiovascular complications.
methodsWe retrospectively analyzed cardiovascular complications in 72 PKTR between 2014 and 2024 at a tertiary center in northern Israel, with follow-up ranging from 1 to 12 years (median 7.3 years). Cardiovascular complications were defined as a composite of post-transplant hypertension requiring pharmacologic treatment, left ventricular hypertrophy (LVH), reduced left ventricular ejection fraction, or aortic root enlargement. Associations between cardiovascular outcomes and demographic, dialysis-related, and transplant-related factors were examined using multivariable logistic regression, including assessment of interaction effects.
resultsPost-transplant hypertension was the most common cardiovascular complication (41.6%), whereas structural or functional cardiac abnormalities were infrequent. A significant interaction was observed between donor type and the need for intensified immunosuppression due to rejection and cardiovascular outcomes (adjusted OR 9.9, 95% CI 1.03-95.6; p = 0.047). Intensified immunosuppression was associated with a markedly higher probability of cardiovascular complications among recipients of living donor grafts, whereas donor type had minimal impact in patients who did not require intensified therapy. No other clinical or dialysis-related variables demonstrated statistically significant associations.
conclusionsIn this contemporary cohort of PKTR, immune-related transplant factors-in particular intensified immunosuppression following living donor transplantation-were associated with post-transplant cardiovascular complications. These findings may incline the importance of vigilant cardiovascular surveillance in PKTR with high immunologic risk profiles. Larger, longitudinal studies are required to clarify the long-term cardiovascular implications of post-transplant risk markers.
