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

Eight Caulobacter crescentus flagellar genes, flmA, flmB, flmC, flmD, flmE, flmF, flmG, and flmH, have been cloned and characterized. These eight genes are clustered in pairs (flmAB, flmCD, flmEF, and flmGH) that appear to be structurally organized as operons. Homology comparisons suggest that the proteins encoded by the flm genes may be involved in posttranslational modification of flagellins or proteins that interact with flagellin monomers prior to their assembly into a flagellar filament. Expression of the flmAB, flmEF, and flmGH operons was shown to occur primarily in predivisional cells. In contrast, the flmCD operon was expressed throughout the cell cycle, with only a twofold increase in predivisional cells. The expression of the three temporally regulated operons was subject to positive regulation by the CtrA response regulator protein. Mutations in class II and III flagellar genes had no significant effect on the expression of the flm genes. Furthermore, the flm genes did not affect the expression of class II or class III flagellar genes. However, mutations in the flm genes did result in reduced synthesis of the class IV flagellin proteins. Taken together, these data indicate that the flm operons belong to a new class of flagellar genes.
