1 · What the graph read from it

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.

2 · The registry

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

The in vitro activity of ceftolozane in combination with tazobactam (fixed concentration of 4 μg/ml) was evaluated against 2,435 Pseudomonas aeruginosa clinical isolates obtained from across Canada using Clinical and Laboratory Standards Institute broth microdilution methods. The MIC50 and MIC90 values for ceftolozane-tazobactam were 0.5 μg/ml and 1 μg/ml, respectively (a 32-fold-lower MIC90 than that for ceftazidime). Eighty-nine percent (141/158) of multidrug-resistant isolates were inhibited by ≤8 μg/ml of ceftolozane-tazobactam.
