Association Between Early Immunosuppression Center Variability and One-Year Outcomes After Pediatric Liver Transplant.
Article in Pediatric transplantation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDespite the existence of institutional protocols, liver transplant centers often have variability in early immunosuppression practices. We aimed to measure within-center variability in early immunosuppression after pediatric liver transplant (LT) and examine its association with one-year outcomes.
methodsWe analyzed pediatric LTs from 2013 to 2018 in the United Network for Organ Sharing registry, with data aggregated by center. We categorized induction regimen as corticosteroids only vs. T-cell depleting antibody vs. non-T-cell depleting antibody. Primary exposures were coefficient of immunosuppression variability (CIV) in (1) induction and (2) mycophenolate mofetil (MMF) use. Primary outcomes were one-year graft survival, patient survival, and acute rejection rate within the first year after transplant.
resultsThe study cohort included 2542 LT recipients from 67 LT centers. Sixteen centers (24%) had no MMF variability; twenty-five centers (37%) had no induction variability. In multivariable analysis, induction CIV was associated with 2.72 times greater odds of acute rejection in the first year (OR 2.72; 95% CI 1.66-4.45; p < 0.001). MMF CIV was not associated with rejection (OR 1.22, 95% CI 0.66-2.25, p = 0.527). Neither one-year graft nor patient survival were associated with induction or MMF CIV.
conclusionsInduction CIV is associated with higher one-year acute rejection odds and did not impact short-term graft or patient survival. Improved understanding of the reasons for high CIV will inform future work aiming to determine whether reducing variability may improve outcomes.
