Characteristics of ESBL-Producing Enterobacterales Colonizing the Gastrointestinal Tract in Patients Admitted to the Oncological Hospital.
Article in Current microbiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
We analyzed the prevalence and genetic characteristics of the extended-spectrum β-lactamases (ESBLs)-producing Enterobacterales isolated from adult patients hospitalized in the oncological center in 2019. Out of 9372 patients admitted to the hospital, 1373 had been in various medical facilities during the last year, which was an indication to perform a screening test for ESBL-producing Enterobacterales colonizing their gastrointestinal tract. In eighty-three patients (6.1%), 85 ESBL producers were detected. These isolates included the following: Escherichia coli (n = 67; 78.8%), Klebsiella pneumoniae (n = 14; 16.5%), Enterobacter cloacae cplx (n = 3; 3.5%), and Klebsiella oxytoca (n = 1; 1.2%). CTX-M-1-like enzymes were the most common ESBLs (n = 67; 78.8%). Two K. pneumoniae isolates (2/85; 2.4%) additionally produced New Delhi-metallo-β-lactamases (NDM). All isolates, except for K. oxytoca, were typed by pulsed-field gel electrophoresis (PFGE) and demonstrated high genetic diversity. The most prevalent phylogroups of E. coli were B2 group (n = 30; 44.8%), followed by A group (n = 25; 37.3%). These observations have motivated us to investigate the link between ESBL-E colonization and infection among patients with solid tumors.
