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

Current analytical techniques are limited in their ability to interrogate the mechanistic relationship between aberrant mucin glycosylation and malignancy. Herein, we describe a method for mapping specific mucin glycoforms in diseased tissue, enabling correlation of the tumor glycan profile with malignant features. Following on-tissue digestion with mucinase StcE, matrix-assisted laser desorption ionization mass spectrometry imaging (MALDI-MSI) deduces the spatial distribution of mucinous O-glycopeptides that are subsequently identified using liquid chromatography coupled to mass spectrometry (LC-MS). Our coupled MS approach reveals a striking mucin 2 (MUC2) expression pattern in three colorectal mucinous adenocarcinomas, in which different glycoforms clearly stratify regions within each tumor. The LC-MS experiments obtain glycoproteomic sequence coverage of MUC2's mucin domains in unprecedented depth, and we also present evidence for an endogenous O-acetylated GalNAc. Overall, this proof-of-concept work underscores the potential of this technique to drive research in oncology and beyond.
