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

The dimorphic bacterium Caulobacter crescentus provides a simple model for cellular differentiation. Each cell division produces two distinct cell types: a swarmer cell and a stalked cell. These cells possess distinct functional morphologies and differential programs of transcription and DNA replication. The synthesis of a single polar flagellum is restricted to the swarmer pole of the predivisional cell by a genetic hierarchy comprising at least 50 genes whose transcription is regulated by novel and ubiquitous promoters, cognate sigma factors, and auxiliary transcriptional regulators. Chromosome replication is restricted to the stalked cell by a unique chromosome origin of replication that may be regulated by a novel cell-specific transcriptional control system. Phosphorylation signals, DNA methylation, differential chromosome structures, protein targeting, and selective protein degradation are also involved in establishing and maintaining cellular asymmetry. The molecular details of these universal cellular processes in C. crescentus will provide paradigms applicable to many general aspects of cellular differentiation.
