Associations between physical and cognitive activities and olfactory function in older adults.
Article in i-Perception. 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
Olfactory function plays a vital role in daily life but tends to decline with age, affecting health and wellbeing. While previous studies suggest a link between physical activities and olfactory function in older adults, the relationship between cognitive activity and olfactory function remains unclear, as do the combined effects of both activities. This cross-sectional study examined associations between physical and cognitive activity and three domains of olfaction (identification, sensitivity, and memory) in 583 community-dwelling older adults. Both types of activity were positively associated with overall olfactory performance. Physical activity exhibited the strongest link with olfaction identification, while cognitive activity was more closely related to olfaction memory. Furthermore, participants engaging in moderate-to-high levels of both activities achieved the best overall olfactory scores. These findings suggest that a combined lifestyle of physical exertion and cognitive engagement may help preserve olfactory function in aging, with implications for autonomy, safety, and quality of life.
