Sporicidal and bactericidal efficacy of plasma-treated liquids based on reaction kinetics of peroxynitrous acid.
Article in Frontiers in microbiology, 2026. 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
Introduction: Plasma-treated aqueous solutions have proven effective for the inactivation of bacteria and even dormant spores. However, reported efficacies vary considerably across setups and experimental conditions. Consequently, different reactive species formed during treatment and their specific reaction kinetics are considered to be responsible. Their individual contribution to microbial inactivation depends on a thorough understanding of the underlying chemical processes. We found that the buffer capacity of an aqueous solution strongly influences the concentrations of reactive species required for effective microbial inactivation. Conversely, the temporal evolution of reactions allows for the optimization of bactericidal and sporicidal efficacy. Methods: Using time-resolved Results: The availability and concentration of peroxynitrous acid (ONOOH) proved crucial for the antimicrobial activity of the liquid. ONOOH generation depends on hydrogen peroxide (H Discussion: Simulations reproduced these experimental trends, confirming three distinct kinetic regimes: a pre-reaction window (before ONOOH formation), a main reaction window (dominated by ONOOH production), and a post-reaction window (defined by decomposition).
