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

A 26-kDa murein hydrolase is the major autolysin of Pseudomonas aeruginosa PAO1, and its expression can be correlated with the growth and division of cells in both batch and synchronously growing cultures. In batch cultures, it is detected primarily during the mid-exponential growth phase, and in synchronous cultures, it is detected primarily during the cell elongation and division phases. Immunogold labeling of thin sections of P. aeruginosa using antibodies raised against the 26-kDa autolysin revealed that it is associated mainly with the cell envelope and in particular within the periplasm. It is also tightly bound to the peptidoglycan layer, since murein sacculi, isolated by boiling 4% sodium dodecyl sulfate treatment, could also be immunogold labeled. Since division is due to cell constriction in this P. aeruginosa strain (septa are rarely seen), we cannot comment on the autolysin's contribution to septation, although constriction sites were always heavily labeled. Some labeling was also found in the cytoplasm, and this was thought to be due to the de novo synthesis of the enzyme before translocation to the periplasm. Interestingly, the autolysin was also found to be associated with natural membrane vesicles which blebbed from the surface during cell growth; the enzyme is therefore part of the complex makeup of these membrane packages of secreted materials (J. L. Kadurugamuwa and T. J. Beveridge, J. Bacteriol. 177:3998-4008, 1995). The expression of these membrane vesicles was correlated with the expression of B-band lipopolysaccharide.
