Rapid Detection and Differentiation of KPC and MBL Carbapenemases among Enterobacterales Isolates by a Modified Combined-Disk Test.

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
This study was conducted to develop a cheap, rapid, and accurate modified combined-disk test (mCDT) approach to detect and differentiate KPC and MBL carbapenemases among clinical carbapenem-resistant Enterobacterales (CRE) isolates and simultaneously distinguish them from carbapenem-susceptible Enterobacterales (CSE) isolates. A total of 163 CRE and 90 third-generation cephalosporin-resistant Enterobacterales isolates were tested using imipenem and meropenem disks and different concentrations of carbapenemase inhibitors. The optimal sensitivity and specificity for detecting KPC carbapenemase were 97.2% and 100%, respectively. The sensitivity and specificity for detecting MBL carbapenemase were 100% and 100% with imipenem or meropenem and carbapenemase inhibitors within six hours. The inhibitory zone diameter of 18 mm for imipenem or meropenem disks without inhibitor could distinguish CRE from CSE isolates. Therefore, this mCDT approach may be a useful tool in clinical laboratories to detect CRE isolates and differentiate KPC and MBL producers, which is beneficial for patient management and hospital infection prevention and control.
