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
<p>Introduction: The aims of the study were to elucidate gene expression changes associated with different stages of calcification in carotid artery plaques and clarify the dynamic biological processes underlying plaque maturation.
methodsCarotid plaque specimens were classified into four groups - mildly, moderately, severely, and very severely calcified - based on calcium scores derived from computed tomography. RNA-Seq (SMART-Seq) analysis and quantitative RT-PCR validation were performed to assess expression profiles of genes related to vascular smooth muscle cell (VSMC) phenotype, inflammation, extracellular matrix (ECM), and calcification.
resultsMildly calcified plaques exhibited elevated inflammatory (CD68, TNF) and osteogenic (RUNX2, SPP1/OPN) gene expression. Moderately calcified plaques showed transient suppression of these genes with upregulation of ELN, suggesting structural stabilization. In severely calcified plaques, osteogenic and inflammatory gene expression persisted, while contractile markers (ACTA2, MYH11) showed limited reactivation. Very severely calcified plaques demonstrated downregulation of VSMC-related genes and selective ECM remodeling, indicating a quiescent, structurally stabilized stage.
conclusionCarotid plaque calcification represents a dynamic, multistage process characterized by reversible and irreversible transitions in VSMC phenotype and ECM composition. These findings emphasize that calcification is not merely passive deposition but reflects coordinated cellular and molecular remodeling, which may inform future stage-specific therapeutic strategies. </p>.
