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
objectiveTo describe an outbreak of multi-drug resistant extended-spectrum β-lactamases-producing Klebsiella pneumoniae (MDR-ESBL-KPN) and the impact of measures for its control.
methodsWe reviewed the patients´ clinical records with MDR-ESBL-KPN isolation during 2013-2016 with resistance to fluoroquinolones, aminoglycosides, fosfomycin, and nitrofurantoin; susceptible to imipenem, meropenem, colistin, and tigecycline and variable to ertapenem and cotrimoxazole (Vitek-2). The genetic relationship between 35 isolates was established by PFGE and MLST. Control measures were put in place in January 2016.
resultsWe detected 269 patients colonized and/or infected by KPN-ESBL-MDR with a common resistance phenotype; the strains studied carried the blaCTX-M-15 gene and formed a single cluster belonging to ST11. The outbreak was detected at the end of 2015, although it began in 2013 in an elderly center. The acquisition source of the strains was: 6% community-acquired, 37% hospital-acquired (76% in internal medicine) and 57% related to long health care facilities (78% of hospitalizations in the last year). Ninety-four percent of patients had at least one underlying disease, 90% received antibiotics previously and 49% had some invasive devices. After the introduction of control measures, the incidence of cases in the quarter was reduced from 29 to 15.
conclusionsWe detected a monoclonal outbreak of MDR-CTX-M-15-KPN in 2015, with predominance of health-care associated cases. The success in the rapid spread of the outbreak was due to the delay in its detection and to the fact that most of the patients had previously received antibiotics. The control measures reduced the number of isolates by 50%.
