Higher model for end-stage liver disease excluding international normalized ratio scores predict worse kidney graft outcomes in simultaneous heart-kidney transplantation.
Article in World journal of 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
backgroundWhile the model for end-stage liver disease excluding international normalized ratio (MELD-XI) is known to be associated with adverse outcomes following cardiac surgery and heart transplantation, its predictive value in outcomes of simultaneous heart-kidney transplant (SHKT) remains unclear. To identify a reliable pre-transplant risk marker for graft and patient survival among SHKT recipients, we hypothesized that higher MELD-XI scores are linked to worse post-transplant outcomes.
aimTo determine the association between MELD-XI and post-transplant outcomes in SHKT recipients.
methodsWe performed a retrospective cohort study in adult SHKT recipients using the United Network for Organ Sharing database from 2014 to 2023. MELD-XI was calculated and categorized into tertiles (high, medium and low). Multivariable Cox proportional hazards models and generalized additive models were used to evaluate the association between MELD-XI and patient mortality and kidney graft failure.
resultsAmong the cohort of 2148 SHKT recipients the MELD-XI tertile distribution was: High (11%), medium (56%), and low (36%). Statistically significant differences among recipients in the highest tertile were seen and they were younger, more frequently female, had higher rates of dialysis, and shorter waitlist times. Recipients in the higher MELD-XI tertile also had significant increase in the delayed kidney graft function and longer hospital stays after transplantation. On multivariable analysis, MELD-XI independently predicted increase in 90-day graft failure, and 1-year graft failure and mortality.
conclusionHigher MELD-XI is associated with increased early mortality and kidney graft failure in SHKT recipients. MELD-XI can provide an objective risk-stratification tool to help identify candidates who should undergo SHKT
