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

Cryptosporidium spp. are waterborne apicomplexan parasites responsible for outbreaks of diarrheal disease worldwide. Antigens involved in zoite invasion into host cells have been the focus of many investigations as these may prove to be good vaccine candidates. gp40/15 is a zoite antigen synthesized as a precursor protein and proteolytically cleaved into the mature glycoproteins, gp40 and gp15. gp15 is anchored in the sporozoite membrane by a glycosylphosphatidyl inositol moiety, while gp40 is predicted to be soluble. However, gp40 bears epitopes that recognize a host cell receptor. If this interaction is important for zoite invasion, then gp40 must have some mechanism of associating with the parasite membrane. In these studies we demonstrate that gp40 and gp15 co-localize to the surface membrane of sporozoites and merozoites, and co-immunoprecipitate, suggesting that these antigens associate after proteolytic cleavage to generate a protein complex capable of linking zoite and host cell surfaces.
