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

backgroundTetraspanins (TSPs), also known as members of the trans-membrane 4 super-family (TM4SF), comprise an assemblage of surface antigens reported in eukaryotic organisms. In the work presented here, six novel TSP proteins from the human blood fluke Schistosoma japonicum (S. japonicum) were produced and analyzed through a combination of bioinformatics and experimental approaches.

resultsSix novel TSP proteins of Schistosoma japonicum (designated as Sj-TSP-#1~6) contained four trans-membrane regions and one large extracellular loop (LEL) with a conserved CCG motif. Size of the proteins varied from 227 to 291 amino acid residues. All the six proteins were produced in E.coli and immune sera to each protein were prepared. Analysis of transcription profiles of the proteins by RT-PCR showed that Sj-TSP-#4 was transcribed only in the egg stage while transcription of the Sj-TSP-#2 was detected in female worms but not in males. The similar results were obtained by Western blot. Immunolocalization of the TSP proteins by immunofluorescence assay showed that the Sj-TSP-#2, Sj-TSP-#5 and Sj-TSP-#6 were located in the tegument of worms.

conclusionsThis study provided six novel TSP members of S. japonicum including their sequences and recombinant proteins. Availability of the novel proteins and information on their expression profile and location provided a basis for further investigation of the TSP proteins for their biological functions and as vaccine candidates.
