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

Interleukin‑6 (IL‑6) is involved in various biological responses, including tumor progression, metastasis and chemoresistance. However, the role and molecular mechanism of IL‑6 in the treatment of sorafenib in liver cancer remain unclear. In the present study, through western blot analysis, Transwell assay, flow cytometric assay, ELISA analysis and immunohistochemistry it was revealed that sorafenib promoted metastasis and induced epithelial‑mesenchymal transition (EMT) in liver cancer cells in vitro and in vivo, and significantly increased IL‑6 expression. Endogenous or exogenous IL‑6 affected metastasis and EMT progression in liver cancer cells through Janus kinase 2/signal transducer and activator of transcription 3 (STAT3) signaling. Knocked out IL‑6 markedly attenuated the pro‑metastasis effect of sorafenib and increased the susceptibility of liver cancer cells to it. In conclusion, the present results indicated that IL‑6/STAT3 signaling may be a novel therapeutic strategy for liver cancer.
