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

aimTo construct a recombinant strain which expresses BabA of Helicobacter pylori (H pylori) and to study the immunogenicity of BabA.

methodsBabA2 DNA was amplified by PCR and inserted into the prokaryotie expression vector pET-22b (+) and expressed in the BL21 (DE3) E.coli strain. Furthermore, BabA immunogenicity was studied by animal test.

resultsDNA sequence analysis showed the sequence of BabA2 DNA was the same as the one published by GenBank. The BabA recombinant protein accounted for 34.8% of the total bacterial protein. The serum from H pylori infected patients and Balb/c miced immunized with BabA itself could recognize rBabA.

conclusionBabA recombinant protein may be an potential vaccine for control and treatment of H pylori infection.
