Association Between Daytime Liver Transplantation and Hospital Length of Stay and Graft and Patient Survival.
Article in The Journal of surgical research, 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
introductionPrior evidence suggests no "daytime effect" in liver transplantation, where the outcomes of daytime transplants are better because of rested surgical teams and the availability of full hospital resources. Daytime transplantation has recently increased with the rapid adoption of normothermic machine perfusion (NMP). The association with patient outcomes and whether this can be attributed to procedural time of day or NMP remains unclear. MATERIALS AND
methodsWe used the United Network for Organ Sharing data for liver transplants between October 2018 and September 2024 to examine the outcomes of daytime (10:00-21:59 reperfusion) versus nighttime (22:00-9:59 reperfusion) transplants.
resultsTransplants with NMP were more likely to occur during the day than those with static cold storage (69.8% versus 54.4%, P < 0.001). After accounting for donor and recipient characteristics using multivariable regression, no significant differences were observed in hospital length of stay or in 90-d patient survival rate between daytime and nighttime transplantation. There was a statistically significant, but not clinically meaningful, decrease in 90-d graft survival for daytime transplantation (94.8 versus 95.2%, relative risk 0.995, P = 0.03).
conclusionsGiven that we observed equivalent outcomes between daytime and nighttime liver transplantation, the potential benefits of daytime liver transplantation may instead be related to nuanced clinical outcomes, such as operative duration and transfusion requirements, and nonclinical outcomes, such as workforce satisfaction, operating room logistics, and hospital finances.
