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

Heteroresistance is a transient resistance phenotype characterized by the presence of small subpopulations of bacterial cells with elevated antibiotic resistance within a susceptible main population. In gram-negative pathogens, heteroresistance is frequently caused by tandem amplification of genes encoding resistance proteins with low activity toward the antibiotic, a process commonly mediated by homologous recombination between flanking repeated sequences. However, the specific roles of individual recombination proteins in this mechanism remain largely undefined. In this study, we systematically evaluated the contribution of 19 recombination-associated genes to tandem amplification-driven heteroresistance in
