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
introductionHuman aortic tissues in vitro are tools to clarify the pathophysiological mechanisms of the cardiovascular system, cell culture, and transplants. Therefore, this study aims to analyze and compare the preservation of human aneurysmatic aortic tissues in three different solutions.
methodsSix human abdominal aortic aneurysms were obtained from patients after surgical ablation. The aorta samples were incubated in different solutions - 0.9% normal physiological saline solution, Ringer's lactate solution, and histidine-tryptophan-ketoglutarate solution (Custodiol®). Segments were collected at 0, 6, 24, and 48 hours. Creatine kinase and nitrate/nitrite were quantified for each incubation time. The tissue's alpha-smooth muscle actin was analyzed by immunofluorescence.
resultsThere was a significant increase in creatine kinase formation in the normal saline group at 0 and 48 hours and in the Ringer's lactate group at 0 and 48 hours (P=0.018 and P=0.028). The lower levels of creatine kinase and nitrate/nitrite and the aortic tissues' morphological integrity show that histidine-tryptophan-ketoglutarate has better tissue protection. These data suggest that histidine-tryptophan-ketoglutarate induces a protective effect on smooth muscle cells, with less tissue depletion in the aortic aneurysm.
conclusionThis study compared three preservation solutions with the potential for human abdominal aortic aneurysm tissue preservation. The histidine-tryptophan-ketoglutarate solution reduced tissue injury and improved tissue preservation in human abdominal aortic aneurysm tissue samples.
