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

Flagellar biogenesis and release are developmental events tightly coupled to the cell cycle of Caulobacter crescentus. A single flagellum is assembled at the swarmer pole of the predivisional cell and is released later in the cell cycle. Here we show that the MS-ring monomer FliF, a central motor component that anchors the flagellum in the cell membrane, is synthesized only in the predivisional cell and is integrated into the membrane at the incipient swarmer cell pole, where it initiates flagellar assembly. FliF is proteolytically turned over during swarmer-to-stalked cell differentiation, coinciding with the loss of the flagellum, suggesting that its degradation is coupled to flagellar release. The membrane topology of FliF was determined and a region of the cytoplasmic C-terminal domain was shown to be required for the interaction with a component of the motor switch. The very C-terminal end of FliF contains a turnover determinant, required for the cell cycle-dependent degradation of the MS-ring. The cell cycle-dependent proteolysis of FliF and the targeting of FliF to the swarmer pole together contribute to the asymmetric localization of the MS-ring in the predivisional cell.
