Changes in activity spaces, life spaces, and exposures to physical activity-promoting environments among women with overweight or obesity.

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
Understanding factors associated with successful adherence and maintenance of weight loss interventions is important to potentially increase efficacy. Activity spaces and environmental exposures are two understudied factors that may be associated with intervention adherence and outcomes. Women with overweight or obesity (n = 498) from two weight loss intervention studies, Reach for Health and Metabolic, Exercise, and Nutrition at University of California San Diego, wore accelerometer and Global Positioning System (GPS) devices for 1 week at baseline and at 6-month follow up. Changes in activity spaces and time spent in three life space domains (Home, Neighborhood, and Beyond Neighborhood) were assessed at the two timepoints for total time and the subset of time in physical activity (PA). Relationships between repeated GPS-measured exposure to PA promoting environments (walkability; recreation; and greenness) were assessed with linear mixed effects models with an interaction between intervention and timepoint. There was no significant change in the average total or PA-related activity space size. There was no significant change in the amount of total time spent in life space domains by intervention group. However, for PA time in life spaces, the Intervention group increased percent of PA time in the Neighborhood (1.49 %-1.71 %; p = 0.011) and Beyond Neighborhood domains (from 5.85 %-6.60 %; p < 0.0001), whereas PA time at Home was not significantly different (p = 0.755). For the mixed effects models with PA-related time, being in the Intervention group was associated with (-0.06, 95 % CI: -0.19, -0.07; p < 0.01) less exposure to walkability and this was attenuated at time 2, compared to controls. Results suggest that PA-focused interventions did not increase the size of participants' total and PA-related activity spaces but were associated with a higher percent of PA-related time outside of the home. There were not consistent associations between the Intervention group and increased exposure to PA-supportive environments.
