Early Morbidity and Survival After Left Lateral Segment Versus Whole Liver Graft Transplantation in Children.
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
backgroundLeft lateral segment (LLS) grafts expand graft availability for infants and small children requiring liver transplantation (LT). However, their cumulative early postoperative burden compared with whole liver grafts (WLGs) remains incompletely characterized.
methodsThis retrospective single-center cohort study included 95 consecutive primary pediatric LT recipients treated between 2019 and 2024, comprising 56 LLS and 39 WLG recipients. Cumulative postoperative morbidity within 90 days was quantified using the Comprehensive Complication Index (CCI). Additional outcomes included biliary and vascular complications, unplanned surgical reinterventions, length of stay, graft loss, retransplantation, and graft and patient survival.
resultsLLS recipients were younger and smaller than WLG recipients. Cumulative 90-day morbidity was greater after LLS transplantation (median CCI 53 vs. 45, p = 0.002). LLS recipients had higher rates of bile leakage (18% vs. 3%, p = 0.024), intra-abdominal bleeding (15% vs. 0%, p = 0.019), and unplanned surgical reintervention (43% vs. 8%, p < 0.001). Although the overall incidence of biliary complications was similar between groups, anastomotic biliary strictures during follow-up were more frequent after WLG transplantation (28% vs. 9%, p = 0.014). Hospital stay was longer after LLS transplantation (median 43 vs. 27 days, p < 0.001). No statistically significant differences in graft loss, retransplantation, or graft and patient survival were detected between groups.
conclusionsLLS transplantation was associated with greater cumulative morbidity within 90 days, characterized by higher rates of bile leakage, intra-abdominal bleeding, unplanned surgical reintervention, and prolonged hospitalization. Despite this greater early postoperative burden, no statistically significant differences in graft loss, retransplantation, or graft and patient survival were detected during the available follow-up. These findings support continued use of LLS grafts to expand transplant access. Given the associated early morbidity, it highlights the importance of an experienced surgical and medical team.
