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

Total nonacid glycosphingolipids were isolated from small intestine mucosal scrapings of a red cell blood group O Le(a-b-) nonsecretor cadaver. Glycolipids were extracted and fractionated into five fractions based on chromatographic and immunostaining properties. These glycolipid fractions were then analysed by thin-layer chromatography for Lewis activity with antibodies reactive to the type 1 precursor (Le(c)), H type 1 (Le(d)), Le(a) and Le(b) epitopes. Fractions were structurally characterized by mass spectrometry (EI-MS and EI-MS/MS-TOF) and proton NMR spectroscopy. EI-MS/MS-TOF allowed for the identification of trace substances in fractions containing several other glycolipid species. Consistent with the red cell phenotype, large amounts of lactotetraosylceramide (Le(c)-4) were detected. Inconsistent with the red cell phenotype, small quantities of Le(a)-5, H-5-1 and Le(b)-6 glycolipids were immunochemically and structurally identified in the small intestine of this individual. By EI-MS/MS-TOF several large glycolipids with 9 and 10 sugar residues were also identified. The extensive carbohydrate chain elongation seen in this individual with a Lewis negative nonsecretor phenotype supports the concept that Lewis and Secretor blood group fucosylation may be a mechanism to control type 1 glycoconjugate chain extension.
