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

Digestive system tumors, which mainly include esophagus, stomach, colorectum, liver, pancreas, bile duct, and some other tumors, often have a poor prognosis. N6-methyladenosine (m6A) has critical functions in development and tumorigenesis and may help improve the molecular mechanisms of digestive system tumors. However, current understanding of the reconstitution of m6A in digestive system tumors is far from comprehensive. Herein, this study systematically analyzed multi-layered genomic characteristics and clinical relevance of m6A regulators in 1906 patients involving seven digestive system tumor types. We discovered that m6A regulators showed extensive genetic changes and highly consistent expression regulation. The m6A expression was closely related to the activity of cancer pathways. At the same time, we also identified m6A regulators significantly related to the common cancer pathways of digestive system tumors and specific cancer pathways of digestive tract and digestive glands. These cancer pathways may explain the prognostic differences of patients with digestive tract tumors. In addition, m6A regulators demonstrated strong potential in prognostic stratification and drug development, especially in multiple research cohorts on pancreatic cancer, pointing to a strong prognostic stratification capability of m6A regulators. Finally, a m6A scoring model significantly related to highly active ubiquitin-mediated proteolysis, mismatch repair, cell cycle, ebasal transcription factors was constructed and had a strong prognostic stratification ability in digestive gland tumors. The score showed a significant negative correlation with the tumor immune microenvironment. This study demonstrated that the similarities and difference of the action mechanism m6A regulators in the digestive tract and digestive gland tumor progression could guide potential drug development.
