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

backgroundEscherichia coli sequence type (ST)131 is an important urinary tract pathogen, and is responsible for considerable healthcare-associated problems and costs worldwide. A better understanding of the factors that contribute to its rapid worldwide spread may help in arresting its continual spread. We studied a large collection of fecal and urinary E. coli ST131 and E. coli non-ST131 phylogenetic group B2 isolates, from women, men and children, in regional NSW, Australia.

resultsWe found out that there was a step up in ST131 prevalence (and possibly in virulence) from fecal to clinical (urinary) isolates in general, and specifically among ciprofloxacin resistant isolates, in the 3 host groups. Furthermore, our results revealed that the inferred virulence potential of the ST131 isolates (as measured by VF gene scores) was much higher than that of non-ST131 phylogenetic group B2 isolates, and this was much more pronounced amongst the urinary isolates. This finding suggests presence of possible E. coli phylogenetic B2 subgroups with varying levels of virulence, with ST131 being much more virulent compared to others. A strong association between ST131 and fluoroquinolone (FQ) resistance was also demonstrated, suggesting that FQ use is related to ST131 emergence and spread. Specifically, about 77% of ST131 isolates from women and men, and 47% from children, were extended spectrum β- lactamase (ESBL) producers. Moreover, FQ resistant ST131 ESBL isolates on average harbored more VF genes than all other isolates.

conclusionsThe strong association between ST131 prevalence and FQ resistance amongst the studied isolates suggests that FQ use is related to ST131 emergence and spread. Furthermore, our results demonstrate that FQ resistance and a plurality of VF genes can exist together in ST131, something that has traditionally been regarded as being inversely related. This may partly contribute to the emergence and worldwide spread of ST131.
