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

Pseudomonas aeruginosa a-type strains produce flagellin proteins which vary in molecular weight between strains. To compare the properties of a-type flagellins, the flagellin genes of several Pseudomonas aeruginosa a-type strains, as determined by interaction with specific anti-a monoclonal antibody, were cloned and sequenced. PCR amplification of the a-type flagellin gene fragments from five strains each yielded a 1.02-kb product, indicating that the gene size is not likely to be responsible for the observed molecular weight differences among the a-type strains. The flagellin amino acid sequences of several a-type strains (170,018, 5933, 5939, and PAK) were compared, and that of 170,018 was compared with that of PAO1, a b-type strain. The former comparisons revealed that a-type strains are similar in amino acid sequence, while the latter comparison revealed differences between 170,018 and PAO1. Posttranslational modification was explored for its contribution to the observed differences in molecular weight among the a-type strains. A biotin-hydrazide glycosylation assay was performed on the flagellins of three a-type strains (170,018, 5933, and 5939) and one b-type strain (M2), revealing a positive glycosylation reaction for strains 5933 and 5939 and a negative reaction for 170,018 and M2. Deglycosylation of the flagellin proteins with trifluoromethanesulfonic acid (TFMS) confirmed the glycosylation results. A molecular weight shift was observed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis for the TFMS-treated flagellins of 5933 and 5939. These results indicate that the molecular weight discrepancies observed for the a-type flagellins can be attributed, at least in part, to glycosylation of the protein. Anti-a flagellin monoclonal antibody reacted with the TFMS-treated flagellins, suggesting that the glycosyl groups are not a necessary component of the epitope for the human anti-a monoclonal antibody. Comparisons between a-type sequences and a b-type sequence (PAO1) will aid in delineation of the epitope for this monoclonal antibody.
