Epidemiology and antimicrobial susceptibility profiles of extended-spectrum beta-lactamase-producing Klebsiella pneumoniae and Escherichiacoli in China.
Article in Brazilian journal of microbiology : [publication of the Brazilian Society for Microbiology], 2019. 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
objectsThe retrospective study aimed to determine the prevalence rate and antimicrobial susceptibility of extended-spectrum beta-lactamases (ESBLs)-producing Klebsiella pneumoniae and Escherichia coli in 2013-2017 at a single center in China.
methodsKlebsiella pneumoniae and Escherichia coli data were collected from the microbiological laboratory. VITEK 2 compact system was used for the identification and antimicrobial susceptibility testing. ESBL status was determined as per the Clinical and Laboratory Standards Institute (CLSI) protocols microdilution method.
resultsAmong a total of 2774 strains of Klebsiella pneumoniae and 2154 strains of Escherichia coli, 15.79% and 36.86% were found to be ESBL producers, respectively. In all patients infected by ESBLs-producing strains, those over 60 years accounted for the largest proportion. Infection by ESBLs-producing Klebsiella pneumoniae was more common in male, while that by ESBLs-producing Escherichia coli was more common in female. Urine and respiratory secretions were the most common sources of ESBLs-producing strains; however, ESBLs-producing strains from urine had been significantly declined. No carbapenem-resistant isolate was found, and all ESBLs-producing strains were resistant to ceftriaxone, aztreonam, and piperacillin. There were no differences in resistance rates between ESBLs-producing Escherichia coli and Klebsiella pneumoniae to ceftazidime and cefepime; however, ESBLs-producing Klebsiella pneumoniae showed higher resistance rates to piperacillin/tazobactam, amikacin, gentamicin, and co-trimoxazole compared with ESBLs-producing Escherichia coli.
conclusionDifferent ESBLs-producing organisms have their own epidemiological characteristics, and the resistance of ESBLs-producing Klebsiella pneumoniae and Escherichia coli is different even to the same antibiotics. Therefore, it is important to continuously monitor the status of ESBLs-producing organisms, and an improved antimicrobial stewardship and infection control are much required.
