Using CMAC Staining for Vacuole Characterization in Yeast.
Article in Methods in molecular biology (Clifton, N.J.), 2026. 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
CMAC (7-amino-4-chloromethylcoumarin) staining is a valuable tool for visualizing acidic organelles, including vacuoles, in yeast cells. By selectively accumulating in acidic compartments, CMAC allows specific labeling and visualization of vacuoles in living or fixed cells, aiding in the investigation of vacuole dynamics, morphology, and distribution under various conditions. This staining method provides a clear contrast against cellular autofluorescence, enhancing imaging clarity. It can be combined with automated imaging capture for faster throughput and analysis.Characterizing vacuole phenotypes using CMAC staining contributes to our understanding of cellular homeostasis and disease mechanisms in yeast. It has applications in studying fundamental cellular processes, including endocytic trafficking and autophagy, as well as in drug screening assays, and can be used in yeast models of disease to offer insights into potential therapeutic targets for diseases affecting the lysosome, including neurodegenerative diseases.
