Layered plaque in patients with chronic coronary syndrome.
Article in Atherosclerosis plus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Plaque disruption exposes thrombogenic substrates and triggers local thrombosis. When a fresh thrombus forms, endogenous antithrombotic mechanisms activate. The balance between these two pro- and antithrombotic mechanisms determines the outcome of plaque disruption. When thrombogenic stimuli outweigh the antithrombotic mechanisms, an occlusive thrombus forms, leading to acute coronary syndromes. When antithrombotic mechanisms dominate, a non-occlusive thrombus forms, contributing to the rapid progression of atherosclerosis. A layered or healed plaque can be identified using optical coherence tomography (OCT). Purpose: The study aimed to investigate the association between atherothrombotic biomarkers and layered plaque at culprit lesions. Methods: We analyzed 119 lesions in patients with chronic coronary syndrome who underwent OCT prior to percutaneous coronary intervention. Four groups of biomarkers were studied: antithrombotic, atherogenic, prothrombotic, and inflammatory. The layer index, defined as the mean layer arc multiplied by the layer length, was assessed using OCT. Results: Patients were divided into tertiles based on each of the four groups. Among the four groups, only the antithrombotic biomarkers were significantly associated with the layer index (low vs. moderate vs. high: 0 vs. 517 vs. 719, Conclusions: The antithrombotic mechanism appears to play a key role in layered plaque formation.
