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

Additive manufacturing has become an important tool in modern medicine with numerous applications such as therapy planning, medical device prototyping and testing, and basic research. While the range of available materials continues to grow, the field of elastic printable materials for medical applications has not been fully explored. Therefore, this study focuses on the comparison of six commercially available flexible printing materials regarding their usability in the medical field. Surface of printed parts for all materials were analyzed directly after printing by scanning electron microscopy. The mechanical behavior was evaluated by uniaxial tensile tests, shore A hardness, and vascular compliance analysis. The degradation effects of the solvents water, glycerin, and ethanol were analyzed over a period of 7 days. The impact of different sterilization protocols (steam, plasma, ethylene oxide) was determined by tensile testing and surface imaging. Cytotoxicity was evaluated by a WST-1 proliferation assay with human endothelial cells. Microscopic imaging revealed a uniform surface with characteristic topologies depending on the printing technique. Different sterilization techniques revealed good results, however, pure silicone material TrueSil
