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 substrate specificities and functions of bacterial efflux pumps are difficult to define due to the large number encoded in bacterial genomes, variations in gene expression, and functional redundancies. In this chapter, we describe the use of efflux-deficient Escherichia coli mutants as simplified genetic backgrounds for studying efflux pumps. We present detailed methodologies for introducing individual efflux pump-encoding genes under constitutive promoters, and we discuss how these strains can be used to examine the physicochemical substrate profiles of drug efflux pumps using susceptibility testing and chemical properties analysis.
