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

A. baumannii is a critical nosocomial pathogen with increasing antibiotic resistance. Colistin heteroresistance (CHR), which cannot be detected by standard methods, threatens the effectiveness of this definitive treatment. This study aimed to characterize carbapenem resistance, detect CHR, and investigate its molecular mechanisms. One hundred forty seven A. baumannii isolates were characterized. Carbapenemase genes were detected by PCR, and antibiotic susceptibility was determined by disc diffusion and broth microdilution. Heteroresistance (HR) was detected using population analysis profiling (PAP). The expression of efflux pump (adeB, adeG) and porin (ompA, carO) genes in HR isolates quantified by Real-time PCR analysis. The predominant carbapenemase genes were bla
