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

Here we provide a protocol for engineering the N-glycosylation pathway of the yeast Pichia pastoris. The general strategy consists of the disruption of an endogenous glycosyltransferase gene (OCH1) and the stepwise introduction of heterologous glycosylation enzymes. Each engineering step results in the introduction of one glycosidase or glycosyltransferase activity into the Pichia endoplasmic reticulum or Golgi complex and consists of a number of stages: transformation with the appropriate GlycoSwitch vector, small-scale cultivation of a number of transformants, sugar analysis and heterologous protein expression analysis. If desired, the resulting clone can be further engineered by repeating the procedure with the next GlycoSwitch vector. Each engineering step takes approximately 3 weeks. The conversion of any wild-type Pichia strain into a strain that modifies its glycoproteins with Gal(2)GlcNAc(2)Man(3)GlcNAc(2)N-glycans requires the introduction of five GlycoSwitch vectors. Three examples of the full engineering procedure are provided to illustrate the results that can be expected.
