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

After mating, many female mammals store a subpopulation of sperm in the lower portion of the oviduct, forming a reservoir. The reservoir lengthens sperm lifespan, regulates sperm capacitation, controls polyspermy, and selects normal sperm. It is believed that sperm bind to glycans on the oviduct epithelium to form the reservoir, but the specific adhesion molecules that retain sperm are unclear. Herein, using a glycan array to test 377 glycans for their ability to bind porcine sperm, we found two glycan motifs in common among all glycans with sperm-binding ability: the Lewis X trisaccharide and biantennary structures containing a mannose core with 6-sialylated lactosamine at one or more termini. Binding to both motifs was specific; isomers of each motif did not bind sperm. Further work focused on sialylated lactosamine. Sialylated lactosamine was found abundantly on the apical side of epithelial cells collected from the oviduct isthmus, among N-linked and O-linked glycans. Sialylated lactosamine bound to the head of sperm, the region that interacts with the oviduct epithelium. After capacitation, sperm lost affinity for sialylated lactosamine. Receptor modification may contribute to release from the reservoir so that sperm can move to the site of fertilization. Sialylated lactosamine was required for sperm to bind oviduct cells. Simbucus nigra agglutinin or an antibody specific to sialylated lactosamine with a preference for Neu5Acalpha2-6Gal rather than Neu5Acalpha2-3Gal reduced sperm binding to oviduct isthmic cells, as did occupying putative receptors on sperm with sialylated biantennary glycans. These results demonstrate that sperm binding to oviduct 6-sialylated biantennary glycans is necessary for normal adhesion to the oviduct.
