FMOD marks a low-malignancy epithelial state in prostate cancer: an ECM-related prognostic signature with single-cell and functional validation.

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
Extracellular matrix (ECM) remodeling promotes prostate cancer progression, while the prognostic value and cellular context of ECM-related genes (ERGs) remain unclear. A 4-gene ERG signature for disease-free interval prediction was built using TCGA-PRAD data, and the hub gene Fibromodulin (FMOD) was validated in an external cohort via scRNA-seq, bulk deconvolution and siRNA knockdown. The signature stratified patient prognosis, and FMOD exerted the strongest protective effect. Despite higher bulk expression in tumor tissues, FMOD predicted better clinical outcomes. FMOD was enriched in a low-chromosomal-instability, low-proliferation epithelial subpopulation with enhanced stromal-immune crosstalk, and FMOD knockdown boosted cancer cell proliferation and colony formation. FMOD identifies a low-malignancy epithelial state linked to favorable prostate cancer prognosis, supporting cell state-resolved validation of ECM-related prognostic biomarkers.
