Sensory deficiencies correlate with tau protein and dementia.
Review in Frontiers in 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
Sensory decline is a common feature of aging and an early sign of a high risk of developing neurodegenerative diseases. Abnormal protein deposits of tau are also observed in sensorial areas in early stages of Alzheimer's disease and related dementia (ADRD), indicating that these two features are associated with common neuropathological changes in the affected brain areas. Alterations in taste and smell are evident in subjects with cognitive decline, but sensory decline is perceived in olfaction, vision, hearing (at early times of degeneration), and even touch, which correlates with disease progression. Consequently, affected individuals may suffer from varying altered behaviors that emerge from the declined capability to process and perceive information, suggesting that differences in sensory perception of the environment may play a key role in explaining these behavioral variations in subjects with cognitive impairment. This commentary discusses some of the alterations in sensory functionality and how these could contribute to the development of neurodegenerative disorders, such as ADRD.
