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

Carbapenemase-producing Enterobacterales (CPE) represent a major global health threat due to limited therapeutic options and high mortality. While isolates harboring a single carbapenemase are increasingly common, polymicrobial bloodstream infections involving multiple carbapenemase-producing species remain rare and pose substantial diagnostic and therapeutic challenges. We describe a case of polymicrobial bloodstream infection in a neutropenic patient with relapsed acute myeloid leukemia. Blood cultures yielded three distinct Enterobacterales species. Identification was performed by MALDI-TOF MS, antimicrobial susceptibility testing followed CLSI guidelines, and carbapenemase production was screened by immunochromatographic assay and PCR. Whole-genome sequencing was conducted for all isolates, with in silico multilocus sequence typing, resistome characterization, plasmid replicon analysis, and phylogenetic reconstruction. A literature review (2015-2025) was performed to contextualize this finding. Three carbapenem-resistant Enterobacterales were simultaneously isolated from blood cultures:
