Oxidative signaling thresholds shape vulnerability in the central and peripheral nervous systems.
Article in PLoS biology, 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
Neurodegeneration is frequently associated with oxidative stress, yet the mechanisms that convert reactive oxygen species (ROS) into irreversible degenerative signals remain incompletely understood. Neurons in the central and peripheral nervous systems often differ in their responses to injury, but these differences cannot be reduced to a simple contrast between weak and strong antioxidant capacity. This Essay proposes that neuronal vulnerability is shaped by multilayered signaling thresholds comprising ROS production, antioxidant and thiol buffering, redox-sensitive signal detection, molecular gating, and commitment to degeneration, survival, or repair. This framework may help explain selective neuronal vulnerability in neurodegenerative diseases and identify intervention points downstream of global ROS suppression.
