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

Glycosylation is a common posttranslational modification of proteins and refers to the covalent addition of glycans, chains of polysaccharides, onto proteins producing glycoproteins. The glycans influence the structure, function, and stability of proteins. They also play an integral role in the immune system, and aberrantly glycosylated proteins have wide ranging effects, including leading to diseases such as autoimmune conditions and cancer. Carbohydrate-active enzymes (CAZymes) are produced in bacteria, fungi, and humans and are enzymes which modify glycans via the addition or subtraction of individual or multiple saccharides from glycans. One of the hurdles in studying these enzymes is determining the types of substrates each enzyme is specific for and the kinetics of enzymatic activity. In this chapter, we discuss methods which are currently used to study the substrate specificity and kinetics of CAZymes and introduce a novel mass spectrometry-based technique which enables the specificity and kinetics of CAZymes to be determined accurately and efficiently.
