Nosocomial Pseudomonas putida Bacteremia: High Rates of Carbapenem Resistance and Mortality.
Article in Chonnam medical journal, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 37 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
Previously, Pseudomonas putida was considered a low-virulence pathogen and was recognized as a rare cause of bacteremia. Recently, however, multidrug-resistant and carbapenem-resistant P. putida isolates have emerged, causing difficult-to-treat nosocomial infections in seriously ill patients. Currently, the outcome of multidrug-resistant or carbapenem-resistant P. putida bacteremia remains uncertain. Here, we report 18 cases of P. putida bacteremia with high rates of carbapenem resistance and mortality. From January 2005 through December 2011, all cases of nosocomial P. putida bacteremia were identified and analyzed at Chonnam National University Hospital and Chonnam National University Hwasun Hospital. Electronic medical records were reviewed retrospectively. Four (22%) and five (23%) of 18 P. putida isolates were resistant to imipenem and meropenem, respectively. Common primary infection sites were central venous catheter (7, 39%), pneumonia (5, 28%), and cholangitis (2, 11%). Fourteen (78%) patients had indwelling devices related to the primary site of infection. The 30-day mortality rate was 39% (7/18): 40% (2/5) in patients with carbapenem-resistant P. putida bacteremia vs. 38% (5/13) in patients with carbapenem-susceptible P. putida bacteremia. Nosocomial P. putida bacteremia showed high resistance rates to most potent β-lactams and carbapenems and was associated with high mortality rates.
