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

objectiveWe evaluated the performance of manual measures of coronary plaque volumes and atherosclerotic plaque features from coronary CT angiography (CTA), using intravascular ultrasound (IVUS) as the reference.

methodsThirty individual coronary plaques with suitable fiduciary markers were identified. Plaque volumes on coronary CTA were manually quantified by two observers and compared to IVUS plaque volumes as interpreted by an independent laboratory. The presence of adverse plaque characteristics-low attenuation plaque (LAP), positive remodelling (PR) and spotty calcification (SC)-on coronary CTA was evaluated and compared to IVUS.

resultsHigh correlation in plaque volumes was detected between observers (r = 0.94, P < 0.0001; 95 % limits of agreement <48.7 mm(3), bias 6.6 mm(3)). Excellent correlation (r = 0.95, P < 0.0001) was noted in plaque volume between independent observers and IVUS (95 % limits of agreement <40.6 mm(3), bias -4.4 mm(3)) and did not differ from IVUS (105.0 ± 56.7 vs. 109.4 ± 60.7 mm(3), P = 0.2). The frequency of LAP (10 % vs. 17 %), PR (7 % vs. 10 %) and SC (27 % vs. 33 %) was similar between coronary CTA and IVUS (all P = NS).

conclusionsPlaque volume on coronary CTA determined by manual methods demonstrates high correlation and modest agreement to IVUS. Further, coronary CTA demonstrates high accuracy for the identification of adverse plaque characteristics, including LAP, PR and SC. KEY POINTS: • Coronary CT angiography is a non-invasive test that enables coronary plaque assessment • Plaque quantification by coronary CT angiography correlates well with intravascular ultrasound findings • Coronary CT angiography can identify adverse plaque characteristics.
