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
backgroundOvarian cancer exhibits striking metastatic tropism for the omentum, where lipid-laden macrophages are key mediators that fuel disease progression. However, the mechanisms governing their formation and pro-metastatic functions remain poorly understood. As extracellular vesicles (EVs) have as critical regulators of tumor-stroma crosstalk in metastatic niches, we sought to define how ovarian cancer-derived EVs orchestrate macrophages and adipocytes, and their impact on omental metastasis, aiming to explore potential therapeutic interventions.
resultsSingle-cell transcriptomics of ovarian cancer revealed a distinct lipid-laden macrophage population in omentum, whose abundance correlated with metastatic burden and poor survival. Proteomics revealed that EVs from highly metastatic ovarian cancer cells were enriched in lipid metabolism regulators. In vivo experiments demonstrated that these tumor-derived vesicles mediated macrophage reprogramming, driving the acquisition of a pro-metastatic phenotype. Quantitative lipidomic profiling and lipid staining approaches confirmed the progressive lipid-laden in EV-treated macrophages. Using a patient-derived omentum-macrophage co-culture system, we demonstrated that tumor-derived EVs stimulate lipid release from omental adipocytes, which macrophages subsequently internalize through CD36-dependent uptake to drive lipid accumulation. This metabolic reprogramming culminated in cellular senescence, as evidenced by classical biomarkers including SA-β-galactosidase activity, elevated p16-INK4A and p53 levels, and the development of a matrix metalloproteinase-enriched senescence-associated secretory phenotype. Immunohistochemistry of clinical specimens demonstrated overexpression of CD36 correlated with omental metastasis and poor survival in ovarian cancer. In vivo experiments demonstrated that CD36 inhibition and senolytic therapy attenuated omental metastasis.
conclusionsThis study unveils an EV-driven mechanism of adipose tropism in ovarian cancer metastasis, where EVs promote the formation of senescent lipid-laden macrophages via CD36-mediated lipid uptake, remodeling the metastatic niche. Targeting CD36 and senescent cells offers a promising therapeutic strategy against omental metastasis.
