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

Persisters are phenotypic variants within bacterial populations that tolerate antibiotic treatments considerably better than the majority of cells. A phenotypic quality that varies within bacterial populations is the chromosome number of individual cells. One, two, four, or more chromosomes per cell have been observed previously, and the impact of genome copy number can range from gene dosage effects to an inability to perform specific DNA repair functions, such as homologous recombination. We hypothesize that chromosome abundance is an underappreciated phenotypic variable that could impact persistence to antibiotics. Here, we describe methodologies to segregate bacterial populations based on chromosome number, assess the purity of those subpopulations, and suggest assays that could be used to quantify the impacts of genome abundance on persistence.
