Galactosides and sialylgalactosides in O-linked oligosaccharides of the primordial germ cells in Xenopus embryos.

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.
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
The primordial germ cells (PGCs) are covered by surface glycoconjugates; some of them, like galactose residues recognized by peanut agglutinin (PNA), have been reported to be implicated in the PGC migration process. The aim of this work was the characterization of galactosides and sialylgalactosides in N- and O-linked oligosaccharides of Xenopus PGCs. Galactose(Gal)- and sialic acid(Neu5Ac)-binding lectin cytochemistry, in combination with chemical and enzymatic deglycosylation methods, were used. PGCs were slightly labeled with PNA, RCA-I and BSI-B4, which suggests the presence of the sequences Gal(beta1,4)GlcNAc and Gal(alpha1,3)Gal. Moreover, there was no labeling when beta-elimination pre-treatment was performed, suggesting that galactosides were in O-linked oligosaccharides. The strong staining with DSA was probably due to GlcNAc. Furthermore, sialylgalactosides with the sequence Neu5Ac(alpha2,3)Gal(beta1,4)GlcNAc in O-linked oligosaccharides have been shown by means of MAA, PNA and RCA-I.
