1 · What the graph read from it

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.

2 · The registry

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

A type-C mold based on in-body tissue architecture was previously developed for preparing small-diameter biotube vascular grafts with a 2-mm diameter and approximately 1-mm wall thickness. In this study, the type-C mold was modified for preparing large-diameter biotubes with controlled wall thicknesses. Four types of molds were assembled by inserting silicone center rods (outer diameters 11, 13, 15, 17 mm) into stainless steel cages (inner diameter 19 mm) and surgically embedded in the abdominal subcutaneous pouches of Holstein cows. After 8-12 weeks, connective tissues occupied the rod-cage gap in the molds to form biotubes. The wall thickness of the biotubes obtained after removing the molds was approximately 1-3 mm, which corresponded to approximately 80% of each gap distance. The breaking strength almost linearly increased with the wall thickness of the biotubes. The strength of the biotubes with wall thickness over 1.5 mm was higher than that of beagle blood vessels. The thickest biotubes were as strong as bovine pericardium and can be used as an alternative trachea graft because of their adequate lumen-holding force.
