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 emergence of the New Delhi metallo-β-lactamase (NDM) among Enterobacteriaceae has become a global concern because of its high levels of in vitro resistance to nearly all available antibiotics. However, recent in vivo studies demonstrated the efficacies of carbapenems against NDM-1-producing isolates despite high MICs. Herein, we report in vivo findings with ceftazidime and ceftazidime-avibactam against an isogenic pair (wild type and NDM-1) and four clinical NDM-producing isolates that demonstrate discordance between MICs measured in vitro and the in vivo activity of ceftazidime-avibactam against this resistant genotype.
