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
Paraquat (PQ) poisoning-induced pulmonary fibrosis is one of the primary causes of death in patients with PQ poisoning. Hypoxia-inducible factor-1α (HIF-1α) and epithelial-mesenchymal transition (EMT) are involved in the progression of pulmonary fibrosis. Snail and β-catenin are two other factors involved in promoting EMT. However, the relationship among HIF-1α, Snail and β-catenin in PQ poisoning-induced pulmonary fibrosis is not clear. Our research aimed to determine whether the regulation of HIF-1α in EMT occurs via the Snail and β-catenin pathways in PQ poisoning-induced pulmonary fibrosis. Sixty-six Sprague-Dawley rats were randomly and evenly divided into a control group and a PQ group. The PQ group was treated with an intragastric infusion of a 20% PQ solution (50 mg/kg) for 2, 6, 12, 24, 48 and 72 hrs. A549 and RLE-6TN cell lines were transfected with HIF-1α siRNA for 48 hrs before being exposed to PQ. Western blotting, real-time quantitative PCR, immunofluorescence, immunohistochemistry and other assays were used in our research. In vivo, the protein levels of HIF-1α and α-SMA were increased at 2 hrs and the level of ZO-1 (Zonula Occluden-1) was reduced at 12 hrs. In vitro, the transient transfection of HIF-1α siRNA resulted in a decrease in the degree of EMT. The expression levels of Snail and β-catenin were significantly reduced when HIF-α was silenced. These data demonstrate that EMT may be involved in PQ poisoning-induced pulmonary fibrosis and regulated by HIF-1α via the Snail and β-catenin pathways. Hypoxia-inducible factor-1α may be a therapeutic target for the treatment of PQ poisoning-induced pulmonary fibrosis.
