Outcomes and learning curve of single-kidney transplantation from small pediatric donors in children: a retrospective cohort study with meta-analysis.
Synthesis in Pediatric surgery international, 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
objectiveTo evaluate clinical outcomes of single-kidney transplantation from small pediatric donors (weight ≤ 15 kg or age ≤ 3 years).
methodsThis retrospective cohort study included 77 children transplanted at our center (Oct 2022-May 2026): 26 small-donor vs. 51 large-donor recipients. CUSUM learning curve analysis and meta-analysis of seven studies (527 patients) were performed.
resultsIn the cohort, small-donor group had lower 1-year graft survival (73.1% vs. 100%, P < 0.001) and higher acute rejection (19.2% vs. 2.0%, P = 0.026), while thrombosis, DGF, and patient survival were similar. EGFR at 1 year was comparable between groups. CUSUM showed an inflection at Case 16 in the small-donor group, with operative time decreasing from 187.6 to 146.3 min. Meta-analysis yielded 1-year patient survival of 98%, graft survival 91%, and pooled thrombosis, DGF, and acute rejection rates of 5%, 13%, and 10%, respectively.
conclusionsEarly graft loss risk in small-donor single-kidney transplantation declines after the learning phase, with acceptable short-term outcomes and high organ utilization. This approach appears feasible in experienced centers, though long-term efficacy requires prospective validation.
