Three-Dimensional Rotary Culture to Model Mycobacterial Biofilms in Low-Shear Detergent-Free Liquid Suspension.
Article in Methods in molecular biology (Clifton, N.J.), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In vitro biofilm models have allowed researchers to investigate the role biofilms play in the pathogenesis, virulence, and antimicrobial drug susceptibility of a wide range of bacterial pathogens. Rotary cell culture systems create three-dimensional cellular structures, primarily applied to eukaryotic organoids, that better capture characteristics of the cells in vivo. Here, we describe how to apply a low-shear, detergent-free rotary cell culture system to generate biofilms of Mycobacterium bovis BCG. The three-dimensional biofilm model forms mycobacterial cell aggregates in suspension as surface-detached biomass, without severe nutrient starvation or environmental stress, that can be harvested for downstream experiments. Mycobacterium bovis BCG derived from cell clusters display antimicrobial drug tolerance, presence of an extracellular matrix, and evidence of cell wall remodeling, all features of biofilm-associated bacteria that may be relevant to the treatment of tuberculosis.
