Efferocytosis-induced metabolic shift in bone macrophages drives lactate production and modulates inflammation and osteoclastogenesis.

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
During the critical process of homeostatic efferocytosis, macrophages clear apoptotic cells and subsequently transition to reparative functions that promote the resolution of inflammation and support tissue repair. Their inherent plasticity enables rapid changes in macrophage activity suited to specific microenvironments. However, the heterogeneity in their cell states also presents challenges in characterizing subsets of macrophages and analyzing their specific contributions post-efferocytosis. In this study, single-cell RNA sequencing data from bone-marrow derived macrophages engulfing apoptotic osteoblasts (OB) was used to characterize macrophage subpopulations enriched during efferocytosis. Clustering analysis revealed two subpopulations (c3 and c9) that were unique to efferocytic macrophages. These distinct subpopulations displayed a transcriptional profile characterized by enhanced glycolytic energy metabolism, along with an anti-inflammatory gene signature. Notably, HIF-1 signaling, glycolysis/gluconeogenesis, and carbon metabolism were among the top five most significantly enriched pathways in c3 and c9 macrophages. qRT-PCR analysis revealed that macrophages engulfing apoptotic OBs exhibited increased expression of key glycolytic enzymes and solute carriers, including
