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

Cisplatin is currently used to treat inoperable recurrent meningiomas, but its side effects and drug resistance limit its use. Metformin has recently been identified as a chemosensitizing agent. However, the combined treatment of cisplatin and metformin in high-grade meningiomas has not been reported. Herein, our findings demonstrate metformin significantly enhanced cisplatin-induced inhibition of proliferation in meningioma cells, which was associated with the induction of G0/G1 cell cycle arrest. Additionally, metformin activated adenosine monophosphate activated protein kinase (AMPK) and repressed the mammalian target of rapamycin (mTOR) signaling pathways via an AMPK-dependent mechanism. Furthermore, our xenograft murine model confirmed that metformin enhanced cisplatin's anti-cancer effect by upregulation of AMPK and downregulation of mTOR signaling pathways. In addition, in 63 patients with atypical meningiomas, the activation of AMPK was significantly associated with tumor recurrence and short disease-free survival (DFS). These results demonstrate metformin enhanced the anti-cancer effect of cisplatin in meningioma
