Benchmarking paediatric living donor liver transplantation for establishing standards to expand access and save lives: retrospective global cohort study.
Article in BJS open, 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
backgroundPaediatric liver transplantation increasingly incorporates technical variant grafts including living donor liver transplantation (LDLT) to address donor shortages. However, the technical complexity of LDLT and regional outcome variations remain challenging. In settings with such variation and ongoing debate, standardized benchmarks may guide decision-making for broader implementation. This study establishes benchmark cut-off values for paediatric LDLT outcomes to provide a validated framework for quality assessment and safe programme expansion.
methodsAn international analysis was conducted of paediatric patients who underwent LDLT at 19 centres between 2019 and 2023. Benchmark cut-off values were derived from 'ideal' patients at seven high-volume institutions, representing the best achievable results under optimal conditions. Surgical complications were graded using the Clavien-Madadi classification, compared against the standard Clavien-Dindo system for accuracy.
resultsIn all, 2665 patients were included, of which 1988 counted as ideal patients. The median recipient age was 10 (interquartile range (i.q.r.) 6-26) months with median weight of 8.0 (i.q.r. 6.6-11.9) kg. Biliary atresia was the most common diagnosis (68.8%), and most recipients (90.9%) received a left lateral segment graft. The 75th percentile of median centre values were used to define the following benchmark cut-off values: hepatic artery thrombosis ≤ 5%, bile leak ≤ 12%, biliary anastomotic stricture ≤ 6%, and 1-year graft loss or mortality ≤ 6%. Higher centre volume was associated with more selective patient inclusion and fewer major (particularly biliary) complications. An inverse correlation between case volume and failure-to-rescue rate highlighted the critical role of multidisciplinary perioperative management. The Clavien-Madadi classification proved superior to the Clavien-Dindo system, which overclassified grade III complications.
conclusionsThis study provides a framework to guide safe programme expansion, improve surgical quality, and reduce waitlist mortality.
