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

backgroundThe clinical relevance of moderate coronary stenosis is determined by its morphological characteristics and physiological significance. We investigated the relationship between high-risk plaque characteristics detected by intravascular ultrasound and functional significance assessed with quantitative flow ratio (QFR) in intermediate coronary lesions.

methodsQFR was retrospectively analyzed in 352 intermediate lesions from 330 patients undergoing intravascular ultrasound examination. The functional significance was defined as QFR ≤0.8. High-risk plaque morphologies including plaque rupture, echo-lucent, echo-attenuation, and spotty calcification were identified, and attenuation indices including maximum angle, attenuation length, and superficial attenuation were determined. Clinically relevant echo-attenuation was defined as an attenuation with a minimum lumen area ≤4.0 mm

resultsThe prevalence of echo-attenuation was higher (63.0%

conclusionsThe presence of intravascular ultrasound-derived echo-attenuation confers an increased risk of QFR-defined functional significance in intermediate coronary lesions. KEYWORDS: Coronary artery disease; intermediate coronary lesion; quantitative flow ratio (QFR); intravascular ultrasound (IVUS); echo-attenuation.
