Dose-response effects of years of self-reported physical activity on old females' motor and cognitive function.
Article in Brazilian journal of physical therapy. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThere is a poor understanding of the dose-response relationship between years of physical activity and motor and cognitive function. We determined the dose-response effects of physical activity duration in years on motor and cognitive function and their relationship in healthy old females.
objectivesTo determine the dose-effects of physical activity duration in years on motor and cognitive function and their relationship in health aging adults.
methodsWe conducted a retrospective observational study with 201 old (age 69 years; SD=5.9) and 12 young (mean age 21 years; SD=1.9) females, with sub-groups based on number of years of self-reported physical activity. Aerobic capacity, mobility, functional reach, standing balance, global cognition, episodic memory, executive function, and processing speed were assessed with performance-based tests. We analyzed sub-group differences quantitatively and qualitatively and performed regression and mediation analyses to determine predictors and mediators of physical activity effects.
resultsBased on physical activity of minimal (0.3 y, n=29), short (2.4 y, n=77), moderate (6.2 y, n=36) and long (16.6 y, n=59) duration, physical activity for at least 2.4 years affords old adults benefits in body mass index with peak dose-effects present in aerobic capacity and mobility at 6.2 years without additional benefits after 16.6 years of physical activity. Physical activity for any duration had no effects on functional reach, balance, executive function, episodic memory, and processing speed. Although weakly mobility predicted global cognition and executive function.
conclusionPerforming physical activity up to 6.2 years on average had favorable effects on body mass index, aerobic capacity and mobility. The data strengthen current recommendations for an active lifestyle in adulthood to prevent aging-related motor and cognitive decline.
