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
Introduction: Periodontitis is the sixth most common human disease and epigenetic regulation is identified to affect the functions of stem cells. This research aims to analyze the role of histone demethylase Lysine-specific demethylase 5A (KDM5A) in human periodontal ligament stem cells (hPDLSCs) with periodontitis. Methods: hPDLSCs were treated with porphyromonas gingivalis-lipopolysaccharide (Pg-LPS) and subjected to osteogenic induction. The expression of KDM5A was detected by RT-qPCR and Western blot. Then, KDM5A expression patterns in hPDLSCs were measured and then silenced using shRNA to explore its role in osteogenic differentiation (OD), proliferation, and migration of hPDLSCs. ChIP assay was used to analyze the relationship between KDM5A and miR-495-3p, Western blot was used to detect H3K4me3 and RT-qPCR was used to detect miR-495-3p expression. CPI-455 (specific KDM5 inhibitor) was adopted to confirm the role of H3K4me3, and dual-Luciferase assay indicted the relationship between miR-495-3p and homeobox C8 (HOXC8). A functional rescue experiment was designed to analyze the role of miR-495-3p in hPDLSCs with periodontitis. Results: KDM5A was highly expressed in LPS-treated hPDLSCs. Downregulation of KDM5A promoted OD, proliferation, and migration of hPDLSCs. Mechanically, KDM5A inhibited miR-495-3p expression by demethylation of H3K4me3 to enhance HOXC8 transcription. Downregulation of miR-495-3p could weaken the effect of sh-KDM5A to promote OD, proliferation, and migration of hPDLSCs. Conclusions: KDM5A could bind to the miR-495-3p promoter and inhibit miR-495-3p expression by demethylation of H3K4me3 to enhance HOXC8 transcription, thereby increasing the HOXC8 and limiting OD, proliferation, and migration of hPDLSCs with periodontitis.
