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
The hazards of particulate matter (PM2.5) on human respiratory health have been previously reported. However, the molecular mechanisms underlying PM2.5-induced lung carcinogenesis have rarely been studied. In the present study, we explored the effects of PM2.5 on the epithelial-mesenchymal transition (EMT) and acquisition of cancer stem cell (CSC)-like properties in lung bronchial epithelial cells. We found that exposure of PM2.5 enhanced lung bronchial epithelial cell proliferation and EMT. In addition, the expression level of CSC-like biomarkers, CD133 and CD44, was significantly elevated by PM2.5 in vitro. Nuclear paraspeckle assembly transcript 1 (NEAT1) has been reported to participate in lung cancer. Loss of NEAT1 represses the malignant transformation of BEAS-2B and HBE cells induced by PM2.5. NEAT1 interacts with microRNA (miR)-582-5p, and miR-582-5p reverses the pro-tumor effects of NEAT1 overexpression. Hypoxia-inducible factor (HIF)-1α is an important transcription factor in the pathological responses to hypoxia. HIF-1α was a predicted target for miR-582-5p, and a direct correlation between them was identified. Inhibitors of miR-582-5p rescued HIF-1α expression, which was attenuated by a lack of NEAT1. In conclusion, PM2.5 increased NEAT1 expression, which, by binding with miR-582-5p, released HIF-1α and promoted EMT and the acquisition of CSC-like characteristics.
