Acquisition of a pathogenicity island in an Escherichia coli clinical isolate causing febrile urinary tract infection.
Article in European journal of clinical microbiology & infectious diseases : official publication of the European Society of Clinical Microbiology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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.
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
Urinary tract infections (UTI) are less common in men than in women, and uropathogenic Escherichia coli (UPEC) is the most frequent etiological agent. Recurrent UTI in men have often been reported as a relapse with the same strain as the index infection. The persistence of the same E. coli strain within the urinary tract has often been explained by a prostatic focus. The aim of this study was to determine whether recurrence was associated with relapse or reinfection and the possible effect of treatment on the content of virulence factors of the isolates causing these infections. Thirty E. coli isolates were collected from 15 patients with a febrile UTI having a bacteriological recurrence during long-term follow-up. These isolates were analyzed by pulsed-field gel electrophoresis (PFGE) and virulence profiling in order to determine whether they constituted relapse or reinfection. Five recurrences were categorized as relapse and nine as reinfections. The results obtained showed that the horizontal transfer of virulence factors contained in a pathogenicity island had occurred in one isolate. This event is possible in vivo and allows bacteria to become more virulent and, perhaps, cause greater damage. The acquisition of virulence genes by horizontal gene transfer is an ongoing process of evolution that continuously leads to new bacterial pathotypes.
