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
BACKGROUND &
objectivesThe emergence and rapid spread of carbapenem resistance mediated by metallo-beta-lactamase (MBL) in Pseudomonas aeruginosa is of major concern due to limited therapeutic options. This study was aimed at detecting the presence of MBL and its association with integrons in imipenem-resistant P. aeruginosa isolates and to determine their genetic relatedness.
methodsA total of 213 P. aeruginosa isolates were collected from two tertiary care centres and tested against anti-pseudomonal antibiotics by antimicrobial susceptibility testing, followed by the detection of MBL production by combined disk method. Minimum inhibitory concentration (MIC) of meropenem was determined by E-test. Multiplex polymerase chain reaction (PCR) was performed for the detection of blaSPM, blaIMP, blaVIM, blaNDM, blaGIM and blaSIM. PCR was carried out to characterize the variable region of class 1 integron. Transcongujation assay was carried out for the confirmation of plasmid-mediated resistance. Enterobacterial repetitive intergenic consensus sequence (ERIC)-PCR was performed for determining the genetic relatedness among P. aeruginosa isolates.
resultsOf the 213 P. aeruginosa isolates, 22 (10%) were found to be carbapenem resistant and these were from pus 18 (82%), urine 2 (9%), sputum 1 (5%) and tracheal wash 1 (5%). Among 22 isolates, 18 (81.8%) were found to be MBL producers by phenotypic method and MIC range of meropenem was 8 to >32 μg/ml. PCR amplification showed that 20 (91%) isolates carried any one of the MBL genes tested: blaVIM and blaNDM in seven (32%) and six (27%) isolates, respectively; blaVIM and blaNDMin three (14%); blaIMP and blaNDM in two (9%); blaVIM and blaIMP in one (5%) isolate. The blaVIM, blaIMP and blaNDM were found to co-exist in one isolate. None of the isolates were positive for blaSPM, blaSIM and blaGIM. All 22 isolates carried class I integron. Of the 20 MBL-positive isolates, transconjugants were obtained for 15 isolates. ERIC-PCR analysis showed all isolates to be clonally independent. INTERPRETATION &
conclusionsOur results showed 10.3 per cent of carbapenem resistance among P. aeruginosa isolates, and the coexistence of MBL-encoding genes among P. aeruginosa mediated by class I integron.
