Escherichia coli sequence type 73 as a cause of community acquired urinary tract infection in men and women in Rio de Janeiro, Brazil.
Article in Diagnostic microbiology and infectious disease, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Escherichia coli clones ST131, ST69, ST95, and ST73 are frequent causes of urinary tract infections (UTI) and bloodstream infections. Specific clones and virulence profiles of E. coli causing UTI in men has been rarely described. The aim of this study was to characterize patient and clonal characteristics of community-acquired UTI caused by E. coli in men (n=12) and women (n=127) in Rio de Janeiro, Brazil, complementing a previous work. We characterized isolates in phylogenetic groups, ERIC2-PCR and PFGE types, MLST, genome similarity and virulence gene-profiles. UTI from men were more frequently caused by phylogenetic group B2 isolates (83% versus 42%, respectively, P = 0.01), a group with significantly higher virulence scores compared with women. ST73 was the predominant clone in men (50%) and the second most frequent in women (12%), with the highest virulence score (mean and median=9) among other clones. ST73 gnomes formed at least six clusters. E. coli from men carried significantly higher numbers of virulence genes, such as sfa/focDE (67% versus 27%), hlyA (58% versus 24%), cnf 1 (58% versus 16%), fyuA (100% versus 82%) and MalX (92% versus 44%), compared with isolates from women. These data suggest the predominance and spread of ST73 isolates likely relates to an abundance of virulence determinants.
