Carbapenemase-Producing Enterobacterales from Patients Arriving from Ukraine in Poland, March 2022-February 2023.
Article in Infectious diseases and therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
introductionDespite a scarcity of data, before 2022 Ukraine was already considered a high-prevalence country for carbapenemase-producing Enterobacterales (CPE), and the situation has dramatically worsened during the full-scale war with Russia. The aim of this study was to analyse CPEs isolated in Poland from victims of war in Ukraine.
methodsThe study included 65 CPE isolates from March 2022 till February 2023, recovered in 36 Polish medical centres from 57 patients arriving from Ukraine, differing largely by age and reason for hospitalisation. All isolates were sequenced by MiSeq and ten Klebsiella pneumoniae isolates also by MinION. Taxonomy, clonality and resistomes were analysed for all CPEs, whereas phylogeny, serotypes, virulomes and plasmids were characterised for K. pneumoniae, and partially for Escherichia coli ST131, using various bioinformatic tools.
resultsMultifactorial diversity of the isolates reflected the patients' clinical-epidemiological heterogeneity. The CPEs represented six species. Klebsiella pneumoniae was the most prevalent with 50 isolates and 15 sequence types (STs), mainly ST395, ST307, ST11, ST147 and ST23, producing NDM (-1/-5), OXA-48 (-48/-1242) or KPC (-2/-3)-like carbapenemases. Each of the STs produced groups of loosely related isolates, clusters of close relatives and/or unique isolates, correlating with K serotypes and carbapenemases. Many of these, especially NDM-1- and/or OXA-48-producing ST395 and ST307, were related to Russian organisms. Others, for example, NDM-1-producing ST11, clustered with those from Poland. Numerous K. pneumoniae isolates had specific virulence genes, including aerobactin iuc, largely due to spread of pNDM-MAR plasmids, showing both resistance and virulence. Two E. coli ST131 isolates belonged to clades B or C1 and produced KPC-3 or NDM-1, respectively.
conclusionsTogether with similar studies from Germany and The Netherlands, this work has documented broad dissemination of CPE in Ukraine, driven by a number of specific K. pneumoniae lineages circulating over a large territory of Eastern Europe.
