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

Carbohydrates are biologically and medicinally important molecules that are attracting growing attention to their synthesis and applications. Unlike the biosynthetic processes for nucleic acids and proteins, carbohydrate biosynthesis is not template-driven, more challenging, and often leads to product variations. In lieu of templates for carbohydrate biosynthesis, we describe herein a new concept of designing enzyme assembly synthetic maps (EASyMaps) as blueprints to guide glycosyltransferase-dependent stepwise one-pot multienzyme (StOPMe) synthesis to systematically access structurally diverse carbohydrates in a target-oriented manner. The strategy is demonstrated for the construction of a comprehensive library of tetraose-core-containing human milk oligosaccharides (HMOs) presenting diverse functional important glycan epitopes shared by more complex HMOs. The tetraose-core-HMOs are attractive candidates for large-scale production and for the development of HMO-based nutraceuticals. To achieve the preparative-scale synthesis of targets containing a Neu5Acα2-6GlcNAc component, a human α2-6-sialyltransferase hST6GALNAC5 is successfully expressed in
