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

Pseudomonas aeruginosa is a major nosocomial pathogen capable of developing multidrug resistance, forming biofilms, and disseminating antimicrobial resistance genes via mobile genetic elements. This study investigated the occurrence, antimicrobial resistance, lecB sequence diversity, and biofilm-forming capacity of environmental P. aeruginosa isolates from three hospitals in Jashore, Bangladesh. Among 231 environmental samples collected from 29 sites in high-risk hospital units, 36 isolates were confirmed by lecB gene sequencing. Sequence analysis classified 77.8% of isolates as PAO1-like and 22.2% as PA14-like, indicating genetic diversity. Biofilm formation was detected in 97.2% of isolates, with no significant difference between strain families. Phenotypic susceptibility testing revealed widespread multidrug resistance, with the highest resistance to ceftazidime (97.2%) and tetracycline (91.7%). Two operation theatre isolates (A40 and 2SW) exhibited extensive drug resistance within the tested antimicrobial panel. Polymerase chain reaction detected blaSHV (55.6%), floR (33.3%), aac(6')-Ib (33.3%), blaTEM (27.8%), and blaOXA-48 (11.1%), while class 1 integrons occurred in 55.6% of isolates and were associated with floR and blaTEM. Whole-genome sequencing identified intrinsic resistance determinants and the mobile resistance genes tmexCD-toprJ and crpP. These findings highlight genetically diverse, multidrug-resistant, integron-positive, biofilm-forming P. aeruginosa in Bangladeshi hospital environments, underscoring the need for routine environmental surveillance and strengthened infection prevention.
