Association between perceived neighborhood environment, sedentary behavior, walking, and moderate-to-vigorous physical activity and frailty: an isotemporal substitution model.
Article in BMC geriatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionWith the rapid increases of older population and growing demand for longevity worldwide, frailty has become a major hurdle to sustaining healthy aging. As residential areas are the primary domains of mobility for older adults, the neighborhood environment is a crucial factor for their daily living and physical activity. This study aims to investigate whether replacing sedentary behavior with physical activity and having a supportive neighborhood environment are associated with frailty status in older adults.
methodsA cross-sectional analysis was conducted with 2,650 participants aged 70-84 years from the Korean Frailty and Aging Cohort Study (KFACS). The main explanatory variables included self-reported physical activity, sedentary behavior (SB), and perceived neighborhood environment. Frailty as the response variable was defined using the Fried frailty phenotype. Multinomial regression was performed to analyze the outcome. The Isotemporal Substitution Model (ISM) was applied to examine the effects of replacing sedentary behavior with physical activity.
resultsThe frailty status of participants was categorized as 45.3% robust, 47.3% pre-frail, and 7.6% frail. Accessibility factor was associated with a decreased risk of being pre-frail (odds ratio (OR): 0.750, 95% CI: 0.673-0.836) and frail (OR: 0.654, 95% CI: 0.541-0.789) compared to being robust. According to ISM, substituting 10 min of SB with any type of physical activity was associated with a reduced risk of pre-frailty [if 10 min of SB was replaced by 10 min of walking (OR: 0.972, CI: 0.960-0.985)] and frailty [if 10 min of SB was replaced by MVPA (OR: 0.877, CI: 0.836-0.921); or by walking (OR: 0.852, CI: 0.814-0.891)].
conclusionsReplacing SB with walking and improving neighborhood accessibility were significantly associated with reduced risk of being pre-frail or frail. These findings highlight the importance of considering these factors when designing age-friendly environments for older adults.
