Effects of Short-Duration Ethanol Dehydration on Mechanical Properties of Porcine Pericardium.
Article in Annals of thoracic and cardiovascular surgery : official journal of the Association of Thoracic and Cardiovascular Surgeons of Asia, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeAutologous pericardium is an ideal material for cardiovascular reconstruction including pulmonary artery plasty. Despite the fact that dehydration by ethanol has been used to improve its surgical handling, the effects of the ethanol on mechanical properties of the pericardium have not been previously investigated. The effects of short-duration ethanol dehydration on the mechanical properties of porcine pericardium were evaluated.
methodsPorcine pericardia (n = 3) were separated into three groups: the raw group with no treatments (RAW), the group immersed in 70% ethanol for 10 min (ET group), and the group immersed in 0.6% glutaraldehyde for 10 min (GA). We measured five parameters of mechanical properties as specified in ISO 7198.
resultsET treatment improved surgical handling as well as GA treatment. There were no significant differences in burst pressure (P = 0.639), suture retention strength (P = 0.529), ultimate tensile strength (UTS; P = 0.486), or Young's modulus (P = 0.408). Only the ultimate strain of the GA group was significantly higher among the three groups (RAW: 33.34% ± 2.02%, ET: 37.48% ± 1.84%, GA: 44.74% ± 2.87%; P = 0.046).
conclusionsShort-duration ethanol dehydration did not compromise its mechanical properties while maintaining its surgical handling improvements.
