Examining the feasibility and preliminary efficacy of a group-based physical activity intervention integrating strength training among pre- and perimenopausal women: A randomized pilot trial.

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
backgroundDespite the well-documented benefits of physical activity, particularly strength training, for managing menopause-related physiological changes such as muscle loss and weight gain, few interventions specifically target pre- and perimenopausal women using scalable, remote delivery methods.
objectivesThe purpose of this pilot study was to examine the feasibility and preliminary efficacy of a group-based physical activity and strength intervention delivered via Zoom for pre- and perimenopausal women.
designThis study was a randomized controlled trial lasting 12 weeks.
methodsLow active pre- and perimenopausal women between the ages of 40-50 (n = 39) were randomly assigned to a 12-week physical activity strength intervention or a waitlist control. Participants attended the sessions twice per week, which included both a 40-min cardiovascular and strength training component and a 20-min motivational component informed by Self-Determination Theory and Habit Formation Theory. Participants were provided Apple Watch devices to monitor their physical activity.
resultsThe physical activity strength intervention appears feasible based on recruitment duration, adherence to the Zoom sessions, retention, and the consumer satisfaction survey. The intervention participants increased their physical activity by 21 min/week, and the control group decreased by 2 min, although the differences were not significant. The intervention participants reported greater positive changes on several of the psychosocial variables, including self-efficacy, habit formation, habit automaticity, self-regulation, goal setting, physical activity enjoyment, physical activity feeling, physical activity revitalization, and physical activity tranquility.
conclusionsAlthough there was no evidence that the intervention led to increases in physical activity, this study supports the feasibility of a group-based physical activity strength intervention delivered via Zoom. Additional studies that include larger sample sizes and a longer intervention are needed to better understand the efficacy of the intervention.
