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

The aim of this study is to analyze post-bifurcation coronary stent morphology in vitro using dual-source CT and validate those findings using micro-CT. Nine silicon coronary artery phantoms simulating main branch (MB) and side branch (SB) were prepared using a 3-D printer. After bifurcation stenting using Crush, Culotte, and T-stenting technique, in vitro CT imaging was conducted using both dual-source CT and micro-CT. Morphological change of the bifurcation stent including crushed segment and floating stent strut were evaluated. Dual-source CT was able to demonstrate morphologic changes of bifurcation stents and was comparable to micro-CT. In stents with Crush and T-stenting methods, crushed segment appeared denser and thicker than other stent parts and was located at MB side in all phantoms. Floating strut was observed in half of the phantoms with Crush technique and all phantoms with T-stenting. Parameters measured in both dual-source CT and micro-CT showed good correlation and high agreement (limits of agreement and correlation for length, perimeter and area, 0.3 ± 3.5, 0.5 ± 2.1 mm, and 0.0 ± 1.5 mm², r = 0.76, 0.92, and 0.91). The morphology of post-bifurcation stent on dual-source CT correlates well with that of micro-CT in the coronary artery phantom. Coronary CT angiography may be a feasible method for the evaluation of stent morphology in patients who underwent bifurcation stenting.
