The Impact of Donor-Recipient Weight Ratios and Body Surface Area Ratios on Outcomes After Adult Deceased Donor Whole-Liver 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
Background: The impact of donor-recipient size mismatch on deceased donor whole-liver transplant (DDLT) outcomes remains underexplored. Weight ratio (WR) is a simple, readily available size-matching metric, whereas body surface area ratio (BSAR) requires additional calculations. We analyzed the impact of donor-recipient WR and BSAR on outcomes among adult DDLT recipients and compared their predictive abilities. Methods: We evaluated adult primary DDLTs in the United Network for Organ Sharing database from January 1, 2013, to January 1, 2024 (n = 69 511). Patients were divided into 5 WR and BSAR percentiles (<10th, 10th-20th, 20th-80th [reference], 80th-90th, and >90th). Cox models assessed associations with graft survival, patient survival, and length of stay (LOS). Kaplan-Meier and receiver operating characteristic (ROC) curves compared outcomes and predictive ability, respectively. Results: WR and BSAR both impacted outcomes. Lower percentiles were associated with modestly decreased graft and patient survival. Graft survival was decreased in the <10th WR percentile (WR ≤0.65; hazard ratio [HR], 1.13; 95% confidence interval [CI], 1.06-1.20; Conclusions: WR and BSAR are both reasonable tools to assess donor-recipient size matching in DDLT. Lower size-matching ratios increased graft failure and mortality, whereas both extremes prolonged LOS. Given its simplicity and immediate availability during donor evaluation, WR may serve as a practical adjunct for donor-recipient size matching. Caution is warranted with WR ≤0.74 or BSAR ≤0.85.
