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

Nitinol frames are often covered with polymer(s) in cardiovascular medical devices to direct blood flow or maintain structural integrity. Due to their insulating properties, coverings pose a challenge to accurately assess the corrosion resistance of the device. Potentiodynamic polarization testing was performed on electropolished and thermal oxide Nitinol stent rings with either an electrospun TPU, dip-coated silicone, or ePTFE/FEP covering to evaluate its impact on Nitinol corrosion resistance. Stent rings were tested fully covered, partially covered (no silicone group), and with the covering removed. For the silicone and ePTFE/FEP groups, uncovered stent rings with a simulated thermal history representative of their covering processes were also tested. The results indicated that breakdown potentials (
