Secondary bacterial infections of Carbapenem-Resistant Acinetobacter baumannii in patients with COVID-19 admitted to Chinese ICUs.
Article in BMC microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundA significant proportion of patients who are hospitalized with coronavirus disease 2019 (COVID-19), particularly those being admitted to ICUs, exhibit the development of secondary bacterial infections (SBIs). However, there is a lack of detailed epidemiological investigations and genetic information of Carbapenem-Resistant Acinetobacter baumannii (CRAB) based on whole genome sequencing (WGS), which is one of the frequently detected bacteria among COVID-19 patients, to confirm alterations in the clonal structure and infection mechanism.
resultsA total of 37 unique CRAB strains, sourced from patients, along with an additional 2 CRAB strains form the environment, were isolated. Among the cohort of 37 patients, 22 individuals succumbed to CRAB infection, resulting in a mortality rate of 54.46%. The median duration of illness for these patients was 7.95 days, highlighting the severity and rapid progression of CRAB infections in this patient population. A total of 22 CRAB strains, isolated from deceased individuals, in addition to two strains isolated from the environment, were subjected to further investigation. All 24 CRAB isolates exhibited a high ability to form biofilm and displayed a similar spectrum of resistance. Except for two isolates from patients with COVID-19, all the remaining CRAB isolates were categorized as ST195 and demonstrated highly close genetic background based on analysis of WGS. The ST195 strain of CRAB harbored three copies of the bla
conclusionsOur findings underscore the significance of SBIs in the COVID-19 pandemic, particularly those caused by CRAB and specifically those belonging to MLST types that were previously prevalent in ICUs.
