Clinical and genomic characterization of Klebsiella pneumoniae infections in Dhaka, Bangladesh.
Article in Journal of global antimicrobial resistance, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
backgroundKlebsiella pneumoniae (Kpn), a WHO priority pathogen with high rates of antimicrobial resistance (AMR), has emerged as a leading cause of hospital acquired pneumonia and neonatal sepsis.
objectiveWe aimed to define the clinical characteristics of a cohort of patients with Kpn infection in Dhaka, Bangladesh and to perform phenotypic and genetic characterization of the associated isolates.
methodsWe retrospectively extracted clinical data about patients at Dhaka Medical College Hospital from whom Klebsiella spp was isolated from a clinical specimen collected between February and September 2022. We used standard microbiologic techniques to evaluate AMR and whole-genome sequencing (WGS) to assess dominant lineages, common capsular (K) and O-polysaccharide (O) antigen types, and AMR and virulence genes.
resultsNinety-eight patients were included, with diagnoses of pneumonia (38/98, 39 %), wound infection (29/98, 31 %), urinary tract infection (29/98, 31 %) and bacteremia (2/98, 2 %). We tested isolates for susceptibility to eight classes of antibiotics. Of the 98 isolates, 41 % were multidrug resistant (MDR), 15 % were extensively drug resistant (XDR), and 16 % were pan-drug resistant (PDR). Three isolates (3 %) were resistant to polymyxin B. Outcome data were available for 46 patients; 4 patients (8 %) died from infections caused by PDR (n = 2), XDR (n = 1), and MDR isolates (n = 1). WGS revealed a high degree of genomic diversity, with multiple sequence types (STs), O-types and K-types represented; ST16:K81:OL101 and ST43:K30:O1 were the most prevalent.
conclusionOur findings suggest alarming levels of AMR among Kpn isolates in Bangladesh and a critical need for improved treatment modalities and vaccine development.
