Association between the frequency of going outdoors by life space and incident disability among older adults.

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
backgroundGoing outdoors is crucial in promoting older adults' health. This study examined the association between incident disability and the frequency of going outdoors in certain life spaces.
methodsThis prospective study included 19,822 older adults (mean age ± standard deviation: 73.5 ± 5.8 years; 53.6 % women). The frequency of going outdoors within the past month was collected based on life space, categorized by distance from home (up to 1 km; 1-10 km; and >10 km). Participants were classified into three groups (called "Rarely": less than 1 day, "Sometimes": 1 to 3 days, and "Often": 4 days or more) for each life space. Incident disability was defined using the Long-Term Care Insurance system data (mean follow-up: 23.3 months). A Cox proportional hazards model was used to examine the association between incident disability and the frequency of going outdoors for each life space, adjusted for covariates.
resultsA total of 1038 (5.2 %) participants had an incident disability. Within the "up to 1 km" category, no frequency group was associated with disability; within "1-10 km," two frequency groups were associated with disability ("Sometimes" group: hazard ratio [HR] 0.85, [95 % confidence interval [CI]: 0.73-0.99]; "Often" group: HR 0.68, [95 % CI: 0.57-0.81]); within ">10 km," similar results were observed ("Sometimes" group: HR 0.84, [95 % CI: 0.72-0.98]; "Often" group: HR 0.75, [95 % CI: 0.53-1.07]).
conclusionsThe frequency of going outdoors at specific distances from home is associated with disability.
