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

In chemotaxis, motile bacteria recognize external molecules and move toward favorable concentrations. Chemoreceptors form complexes that perform transmembrane signaling, control a histidine kinase, and undergo posttranslational adaptational modifications. Chemoreceptors are thought to function by switching between two signaling states: kinase-off, favored by ligand occupancy, and kinase-on, favored by adaptational modification. Many structural and biochemical features of the two states have been identified, but little is known about the equilibrium between them and the response of that equilibrium to signaling inputs. Using single-molecule Förster resonance energy transfer, we monitored helical separations in the
