Insights into colistin-mediated fluorescence labelling of bacterial LPS.
Article in RSC advances, 2024. 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
Gram-negative bacterial infections are becoming untreatable due to their ability to mutate, and the gradual development of their resistance to the available antimicrobials. In recent times colistin, a drug of last resort, started losing its efficacy towards multidrug-resistant bacterial infections. Colistin targets bacterial endotoxin lipopolysaccharides (LPS) and destabilises the cytoplasmic membrane by disrupting the outer LPS membrane. In this study, we have tried to label the bacterial LPS, the main constituent of the cytoplasmic membrane of bacterial cells, to try to understand the interaction mechanism of LPS with colistin. The chemosensor, naphthaldehyde appended furfural (NAF) that selectively recognises colistin can label LPS, by showing its fluorescence signals. The computationally derived three-dimensional structure of LPS has been introduced to speculate on the possible binding mode of colistin with LPS, and this was also thoroughly studied with the help of quantum mechanics and molecular dynamics energy minimisation. Fluorescence microscopy and FE-SEM microscopic studies were also used to observe the change in the structural morphology of colistin-sensitive and resistant
