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
Polymorphisms of mouse chitinase-like protein 3 (Chil3), a member of the mammalian chitinase-like protein (CLP) family, have been demonstrated to be associated with inflammatory diseases by regulating lipid metabolism. However, the specific immunomodulatory impacts of CLPs, mainly mouse CHIL3 and its human functional homologue chitinase-3-like 2 (CHI3L2), on macrophage cholesterol metabolism and atherosclerosis have remained unclear. Here, we find CLPs (CHIL3 and CHI3L2) accelerate atherogenesis in a macrophage-dependent manner. Mechanistically, we identify an autocrine mechanism through which CLPs regulate cholesterol metabolism in macrophages. Macrophage-secreted CLPs exacerbate lipid uptake by binding to CD36. CLPs exhibit glycosidase activity, targeting and hydrolyzing N-glycosylated glycans on CD36, predominantly at sites N220 and N321, thereby enhancing lipid uptake. Increased lipid influx activates mTOR in macrophages, driving their transition to a pro-inflammatory phenotype while simultaneously suppressing peroxisome proliferator-activated receptor gamma (PPARγ) expression and thus impairing ABCG1-mediated cholesterol efflux. Single-cell sequencing reveals that CLPs increase atherosclerotic foamy macrophages, favoring vascular smooth muscle cells (VSMC) transformation into foam and osteoblast-like cells. Additionally, neutralizing antibodies targeting CHI3L2 prevent and treat atherosclerosis. These findings highlight the potential of CLPs as targets for disease diagnosis and therapy.
