1 · What the graph read from it

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.

2 · The registry

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 aim of the present study was to investigate the anti‑fibrotic effects of astragaloside IV (ASV) in silicosis rats, and to further explore the potential underlying molecular mechanisms. A silica‑induced rat model of pulmonary fibrosis was successfully constructed. Hematoxylin and eosin and Masson's trichrome staining were performed to observe the pathological changes in lung tissues. Immunohistochemical analysis was used to assess the expression levels of Collagen I, fibronectin and α‑smooth muscle actin (α‑SMA). A hemocytometer and Giemsa staining were used to evaluate the cytological characteristics of the bronchoalveolar lavage fluid. ELISA was used to detect the levels of the inflammatory cytokines tumor necrosis factor‑α, interleukin (IL)‑1β and IL‑6. Reverse transcription‑quantitative PCR and western blotting were performed to detect the mRNA and protein expression levels of genes associated with the transforming growth factor (TGF)‑β1/Smad signaling pathway. ASV alleviated silica‑induced pulmonary fibrosis, and reduced the expression of collagen I, fibronectin and α‑SMA. In addition, the results of the present study suggested that the ASV‑mediated anti‑pulmonary fibrosis response may involve reduction of inflammation and oxidative stress. More importantly, ASV suppressed silica‑induced lung fibroblast fibrosis via the TGF‑β1/Smad signaling pathway, thereby inhibiting the progression of silicosis. In conclusion, the present study indicated that ASV may prevent silicosis‑induced fibrosis by reducing the expression of Collagen I, fibronectin and α‑SMA, and reducing the inflammatory response and oxidative stress, and these effects may be mediated by inhibiting the activation of the TGF‑β1/Smad signaling pathway.
