Pharmacokinetics of Meropenem in People with Cystic Fibrosis-A Proof of Concept Clinical Trial.

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
Anti-infective treatment of pulmonary exacerbations is a major issue in people with cystic fibrosis (CF). Individualized dosing strategies and adaptation of infusion times are important concepts to optimize anti-infective therapy. In this prospective non-randomized controlled open-label trial, we compared pharmacokinetics of meropenem in 12 people with CF experiencing a pulmonary exacerbation, of whom six received parenteral meropenem 2 g tid as short infusion over 30 min and six extended infusion over 120 min. We measured blood concentrations of meropenem at five predetermined time points over 240 min and calculated differences in the percentages of the time above the minimal inhibitory concentration (fT > MIC) for meropenem concentrations >16 and >32 mg/L, respectively. Mean percentages of fT > 16 and fT > 32 mg/L were higher in the extended compared to the short infusion group (83 and 56% vs. 59% and 34%), with a statistically significant prolongation of the fT > 32 mg/L (mean 134 vs. 82 min;
