Observational study in BMC microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04310722 (Dissemination and Resistance Mechanisms of Carbapenem-resistant Gram-negative Bacilli and Methicillin-resistant Staphylococcus Aureus in Intensive Care Units in China), which is not on this map. Not yet cited in PubMed.

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.

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.

Abstract

backgroundCarbapenem-resistant Acinetobacter baumannii (CRAB) poses significant challenges in intensive care units (ICU) due to its multidrug resistance and environmental persistence. To date, most studies have focused on clinical isolates or patient-environment transmission. However, high-touch mobile surfaces have been less extensively characterized.

resultsWe collected 49 CRAB isolates in 2019 and 2021 from ICU patients (n = 32) and trolley surfaces (n = 17). 91.84% (45/49) isolates belonged to ST2

conclusionsThese findings demonstrate the coexistence of closely related CRAB on patients and trolley surfaces within the same ICU and highlight the importance of considering high-touch mobile surfaces in infection prevention and control (IPC) strategies.
