The emerging role of ubiquitin-proteasome system dysfunction in the pathogenesis of perioperative neurocognitive disorders: a narrative review.
Review in Frontiers in behavioral neuroscience, 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
Perioperative neurocognitive disorder (PND) is a prevalent and serious complication affecting the central nervous system following surgery, particularly among elderly patients. PND has a significant impact on patient prognosis and places a substantial burden on both individuals and the healthcare system. Despite its importance, the complex pathological mechanisms underlying PND remain inadequately understood, and there are currently no effective prevention or treatment strategies available. One critical factor contributing to PND is the imbalance in protein homeostasis, with the ubiquitin-proteasome system (UPS), recognized as the primary mechanism for protein quality control within cells. This review systematically discusses the crucial role of UPS dysfunction in the development of PND. Additionally, it analyzes potential biomarkers for diagnosing PND and explores treatment strategies targeting the UPS. This provides a new perspective for a deeper understanding of the molecular mechanisms involved in PND and lays a theoretical foundation for the development of new intervention methods.
