Correlation between coronary angioscopy yellow grade and lipid plaque assessment by integrated backscatter intravascular ultrasound.

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.
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
Coronary angioscopy (CAS) enables direct qualitative assessment of the coronary artery lumen, while integrated backscatter intravascular ultrasound (IB-IVUS) provides a quantitative evaluation of coronary plaque tissue characteristics. Despite the utility of both techniques in assessing coronary plaque status, data on the correlation between their findings remain limited. To investigate the association between CAS-derived findings and results obtained through IB-IVUS. This retrospective analysis included 36 patients who underwent both CAS and IB-IVUS during percutaneous coronary intervention (PCI) at our institution. CAS and IB-IVUS were performed on the same coronary artery treated during PCI. Plaques were categorized into four groups based on their yellow color grade using CAS. For the IB-IVUS analysis, measurements were performed at the minimum lumen diameter site of the culprit lesion. A significant correlation was observed between plaque yellowishness and plaque characteristics on IB-IVUS. Higher plaque yellowishness was associated with an increased percentage of all lipid pool (P < 0.01), a greater proportion of attenuated plaque (P < 0.01), and a larger estimated lipid plaque volume (P < 0.01). Additionally, plaques with higher yellowishness grades had significantly thinner fibrous caps (P < 0.01). The findings suggest that higher plaque yellowishness observed via CAS correlates with a larger lipid plaque volume and thinner fibrous caps, as assessed through IB-IVUS.
