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
This study is expected to investigate the role of miR-30e-5p in chronic periodontitis (CP) and its diagnostic value in CP. First, the level of miR-30e-5p in CP patients was analyzed, and its ability in the clinical diagnosis of CP was analyzed by Receiver Operating Characteristic (ROC) curve. Subsequently, osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs) was induced in vitro. Then, the effect of miR-30e-5p on cell proliferation, apoptosis, ALP activity and osteogenic differentiation markers were analyzed by CCK-8, flow cytometry, commercial kit and RT-qPCR. To investigate whether miR-30e-5p and chromosome helicase DNA binding protein 7 (CHD7) have a targeted relationship, we performed double luciferase reporting and RNA immunoprecipitation assays. Finally, the mechanism of miR-30e-5p and CHD7 jointly regulating osteogenic differentiation of hPDLSCs was investigated in vitro. Compared with healthy controls, the periodontal status of CP patients was worse and the level of miR-30e-5p was higher. The sensitivity and specificity of miR-30e-5p for predicting CP were 76.67% and 80.00%. In addition, the level of miR-30e-5p gradually decreased during the induction of osteogenic differentiation. Inhibiting the expression of miR-30e-5p increased the cell viability of hPDLSCs, and increased the activity of ALP and the level of osteogenic differentiation markers. However, the downregulation of CHD7 reversed a series of results associated with the downregulation of miR-30e-5p. In periodontitis, miR-30e-5p may impede osteogenic differentiation of hPDLSCs by regulating CHD7. Moreover, miR-30e-5p may be a diagnostic biomarker for CP.
