Article in BMJ open, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02496741 (Phase Ib Study of Metformin and Chloroquine in IDH1/2-mutated Patients With Glioma, Intrahepatic Cholangiocarcinoma or Chondrosarcoma), which is not on this map. Cited by 50 papers.

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.

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.

Abstract

introductionHigh-grade chondrosarcoma, high-grade glioma and intrahepatic cholangiocarcinoma are aggressive types of cancer with a dismal outcome. This is due to the lack of effective treatment options, emphasising the need for novel therapies. Mutations in the genes METHODS AND ANALYSIS: We describe a dose-finding phase Ib/II clinical trial, in which patients with ETHICS AND DISSEMINATION: This study has been approved by the medical-ethical review committee of the Academic Medical Center, Amsterdam, The Netherlands. The report will be submitted to a peer-reviewed journal. TRIAL REGISTRATION NUMBER: This article was registered at ClinicalTrials.gov identifier (NCT02496741): Pre-results.
