Continuous infusion of ceftolozane-tazobactam resulted in high cerebrospinal fluid concentrations of ceftolozane in a patient with multidrug-resistant Pseudomonas aeruginosa meningitis.

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
Multidrug-resistant Pseudomonas aeruginosa has limited treatment options. Treatment of healthcare-associated meningitis requires agents active against the organism in vitro and able to penetrate the cerebrospinal fluid adequately. Ceftolozane-tazobactam has been recently approved to treat various Gram-negative organisms, including Pseudomonas aeruginosa; however, ceftolozane's penetration into human cerebrospinal fluid is unknown. Here, we present a case of a patient with multidrug-resistant Pseudomonas aeruginosa meningitis treated with a continuous infusion of ceftolozane-tazobactam. Samples of both serum and cerebrospinal fluid were analyzed for ceftolozane concentration on continuous infusion. Cerebrospinal fluid concentrations of ceftolozane were 83% of that in serum. Treatment with ceftolozane-tazobactam, along with combinations of other antibiotics, resulted in clearance of organism from the patient's cerebrospinal fluid and marked decrease in inflammatory cells. Studies are warranted to determine the efficacy of ceftolozane-tazobactam for patients with healthcare-associated meningitis.
