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

This review examines the current two leading hypotheses relating to cancer neogenesis-the somatic mutation theory (SMT) and the tissue organization field theory (TOFT)-and focuses on four specific issues. What are the details of the process that changes the epigenetic cargo of the exosomes a cell produces when it becomes malignant? Can exosomes produced by a malignant cell induce on their own a metastatic cancer in the target tissue? What is the functional significance of the fact that exosomes from cancer cells carry in their loads segments of genomic DNA bearing cancer-related mutations across the entire spectrum? What is the evolutionary advantage for the organism of the production by its cancer cells of exosomes that carry epigenetic instructions for the building of elaborate molecular mechanisms that promote the growth of metastatic cancers? These issues are examined with a view of determining the support they give to one or other of the two hypotheses. The conclusion is that they support a specific form of TOFT in which exosomes play a key role.
