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

Some proteins undergo conformational changes when they bind their cognate ligand. This conformational change can be coupled to changes in the local environment of the chromophore of green fluorescent protein (GFP) to create genetically encoded sensors for those ligands. The periplasmic binding proteins of bacteria bind diverse classes of molecules and have been made into sensors for a number of neurotransmitters and metabolites. Here we describe protocols for using these sensors to quantify analytes in complex solutions in vitro and how to use them in cell culture-based assays to observe fluctuations in their concentration over time, from the millisecond existence of neurotransmitters to the consumption of cytosolic metabolites over the course of hours.
