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
objectiveNeuropathic pain typically develops after nerve injury and is largely driven by microglial activation in the central nervous system (CNS), with colony-stimulating factor 1 (CSF1) serving as a key initiator. We analyzed mRNA and microRNA expression profiles in CSF1-stimulated primary microglia using next-generation sequencing, followed by integrative bioinformatic analyses.
methodsRat microglia were cultured in microglial medium at 37°C with 5% CO
resultsCSF1 stimulation altered the expression of 176 miRNAs and 429 mRNAs, including 86 upregulated and 90 downregulated miRNAs. Inverse correlation analysis revealed 68 downregulated miRNAs linked to 119 upregulated mRNAs, and 69 upregulated miRNAs linked to 204 downregulated mRNAs, indicating complex regulatory interactions. The transcriptional program induced by CSF1 was characterized by increased expression of proinflammatory and proliferative genes, such as Fos, Cxcl2, and Ephb3, and suppressed expression of ECM- and glycosaminoglycan (GAG)-related genes, including Gpc6 and Prelp. Several miRNAs, including rno-miR-652-5p, rno-miR-672-5p, rno-miR-455-3p, rno-miR-145-5p, rno-miR-222-3p, rno-miR-702-5p, rno-miR-877, rno-miR-664-2-5p, and rno-miR-702-3p, emerged as potential upstream regulators of these changes. Pathway enrichment analysis highlighted the activation of TNF, IL-17, and mitogen-activated protein kinase (MAPK) signaling, coupled with the suppression of ECM remodeling.
conclusionThese findings identify candidate miRNA-mRNA regulatory networks associated with CSF1-driven microglial responses and provide new insights into transcriptomic changes relevant to neuroimmune mechanisms in neuropathic pain.
