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

Resistance to β-lactam antibiotics through β-lactamase production by Enterobacteriaceae continues to burden the health-care sector worldwide. Traditional methods for detection of β-lactamases are time-consuming and labor-intensive and newer methods with varying capabilities continue to be developed. The objective of this study was to develop a multiplex PCR (M-PCR) system for the detection of blaSHV, blaTEM, blaCTX-M-1, blaCTX-M-9 and blaOXA-1 group genes and to apply it in clinical Klebsiella pneumoniae and Escherichia coli strains. To do this, we used group-specific PCR primers in singleplex reactions followed by optimization into multiplex reactions. Specificity and sensitivity of the M-PCR were then evaluated using 58 reference strains before its application to detect bla group genes in 203 clinical Enterobacteriaceae strains. PCR amplicons were sequenced to determine the β-lactamase subtypes. The M-PCR system exhibited 100% specificity and sensitivity. In all, 83.7% of K. pneumoniae and 89.8% of E. coli clinical strains harbored bla group genes with 46.9%, 40.1%, 15.0%, 21.1% and 6.1% of K. pneumoniae having blaSHV, blaTEM, blaCTX-M-1, blaCTX-M-9 and blaOXA-1 group genes, respectively, whereas 12.2%, 77.6%, 22.4%, 36.7% and 8.2% of E. coli had blaSHV, blaTEM, blaCTX-M-1, blaCTX-M-9 and blaOXA-1 group genes, respectively. BlaSHV-1, blaSHV-11, blaSHV-27, blaSHV-33, blaSHV-144, blaTEM-1, blaTEM-135, blaOXA-1, blaCTX-M-3, blaCTX-M-9, blaCTX-M-14, blaCTX-M-15, blaCTX-M-27, blaCTX-M-55, blaCTX-M-65 and blaCTX-M-104 were detected. In conclusion, the M-PCR system was efficient and versatile with an advantage of simultaneously detecting all the targeted bla group genes. Hence, it is a potential candidate for developing M-PCR kits for the screening of these genes for clinical or epidemiological purposes.
