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

Examination of Bacillus subtilis strains containing multiple mutations affecting the class A high-molecular-weight penicillin-binding proteins (PBPs) 1, 2c, and 4 revealed a significant degree of redundancy in the functions of these three proteins. In rich media, loss of PBPs 2c and 4 resulted in no obvious phenotype. The slight growth and cell morphology defects associated with loss of PBP 1 were exacerbated by the additional loss of PBP 4 but not PBP 2c. Loss of all three of these PBPs slowed growth even further. In minimal medium, loss of PBPs 2c and 4 resulted in a slight growth defect. The decrease in growth rate caused by loss of PBP 1 was accentuated slightly by loss of PBP 2c and greatly by loss of PBP 4. Again, a lack of all three of these PBPs resulted in the slowest growth. Loss of PBP 1 resulted in a 22% reduction in the cell radius. Cultures of a strain lacking PBP 1 also contained some cells that were significantly longer than those produced by the wild type, and some of the rod-shaped cells appeared slightly bent. The additional loss of PBP 4 increased the number of longer cells in the culture. Slow growth caused by a mutation in prfA, a gene found in an operon with the gene encoding PBP 1, was unaffected by the additional loss of PBPs 2c and 4, whereas loss of both prfA and PBP 1 resulted in extremely slow growth and the production of highly bent cells.
