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

Gliomas and brain-metastatic tumors contribute to hundreds of thousands of deaths every year. Typical survival times for brain cancer patients, even with surgical, chemotherapy, and radiation treatment, remain very low despite advances in treatment. In brain cancers, astrocytes, which comprise approximately 50 % of the cells in the brain, become activated, resulting in a layer of reactive astrocytes surrounding the tumor. This process of reactive gliosis, which involves the secretion of growth factors and cytokines, helps repair injury in the brain, but also plays a role in disease progression. In this review, we survey the mechanisms by which astrocytes modulate the local tumor microenvironment, enhancing proliferation, invasion, chemoprotection, and immunoprotection of tumor cells. Consideration of the effect of astrocytes and reactive gliosis in in vitro and in vivo assays may allow us to obtain a more complete picture of the interactions occurring at the tumor microenvironment, which will provide additional insight into potential pathways that can be targeted by brain cancer therapeutics.
