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

Colistin resistance in Gram negative bacteria is mainly attributed to chromosomal mutations in Two Component Systems(TCS) PhoPQ and PmrAB and plasmid-borne genes(mcr and its variants). The aim of this study was to understand the molecular basis of colistin resistance in Klebsiella pneumoniae and determine clonal transmission, in a North Indian tertiary care hospital over a 2.5 year period. Antimicrobial susceptibility was determined by Vitek and colistin resistance was confirmed by broth microdilution. Carbapenemases(bla
