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

We investigated the colistin resistance of Klebsiella pneumoniae blood isolates from South Korea. Among 252 K. pneumoniae isolates, only 11 (4.4%) demonstrated colistin resistance, of which, one was resistant to all antibiotics but tigecycline. Multilocus sequence typing analysis revealed ten sequence types among the 11 colistin-resistant isolates, indicating independent occurrence of colistin resistance in K. pneumoniae. To understand the mechanism of colistin resistance, amino acid variations in PmrAB, PmrD, PhoPQ, and MgrB were investigated. Amino acid substitutions were identified in all the colistin-resistant K. pneumoniae isolates. Particularly, extensive alterations in the genes associated with colistin resistance were shared in four colistin-resistant isolates, suggesting recombination between these genes of unrelated isolates. Our results suggest that genetic recombination is responsible for colistin resistance in some K. pneumoniae isolates.
