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
There is increasing interest in developing therapeutic interventions aimed at preventing neuroinflammation in Parkinson's disease (PD). However, the specific characteristics of inflammation across different cell types and the underlying mechanisms of PD-related inflammation remain inadequately understood. In this study, we conducted an analysis of single-cell RNA sequencing (scRNA-seq) and microarray data derived from human PD midbrain tissue, specifically focusing on the substantia nigra compacta (SNc). These datasets were sourced from the (GEO) database. We utilized GSVA, GSEA, as well as KEGG and GO analyses to explore transcriptional variations associated with PD. Furthermore, trajectory and SCENIC analyses were conducted to uncover the mechanisms underlying PD progression. Subsequent animal and cellular experiments validated the role of the regulon in regulating neuroinflammation. Results: Our analysis revealed that microglia displayed the highest levels of inflammatory activity, characterized by an increased abundance of microglia in the proinflammatory activated state within the midbrain and SNc of PD patients. This finding was further validated in a PD mouse model induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). The transcription factor STAT3 demonstrated significant upregulation and was implicated in promoting the inflammatory response and activating microglia within the PD context. In the 1-methyl-4-phenylpyridine (MPP +)-induced BV2 cell model, inhibition of STAT3 led to reduced levels of inflammation, hindered STAT3 phosphorylation, and decreased the production of inflammatory factors. Furthermore, the downregulation of P-STAT3 alleviated the harmful effects on SH-SY5Y cells that were cocultured in the conditioned medium. Conclusions: Our study underscored the pivotal role of the transcription factor STAT3 as a central regulator of proinflammatory activation in microglia within PD. These findings offer fresh insights into PD pathogenesis and suggest potential avenues for the development of novel therapeutic strategies.
