Quantifying Staphylococcus aureus Membrane Potential Using Flow Cytometry.
Article in Methods in molecular biology (Clifton, N.J.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Quantifying fluorescent markers in cell populations using flow cytometry has been a powerful technological advance. Fluorescent properties of cyanine dyes coupled with flow cytometry allow investigators to monitor the membrane potential (MP), an important component of the proton motive force (PMF). MP (or ΔΨ) is the electrical potential across the cell membrane. The other component of the PMF is ΔpH, or the difference in interior and exterior proton concentrations. MP plays a critical role in bacterial physiology. In Staphylococcus aureus, MP is required for generation of ATP, regulating autolytic activity, maintaining ion homeostasis, and resistance to some classes of antibiotics. This protocol exploits unique spectral and physical properties of the cyanine-based molecule diethyloxacarbocyanine iodide, or DiOC, and flow cytometry technology to quantify MP in S. aureus. This assay has been used by researchers to define the electron transport chain of S. aureus as well as determine how intrinsic and extrinsic factors affect MP.
