1 · What the graph read from it

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.

2 · The registry

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

objectivesWith population aging, personalized exercise programs considering clinical and demographic factors like sex, age, and physical activity level are essential; however, research on their effects remains limited. We aimed to evaluate the effectiveness of a Global Physical Activity Questionnaire-based graded personalized exercise program tailored for middle-aged adults aged 40-69 years.

participantsWe enrolled 71 middle-aged adults in their 40s, 50s, and 60s (approximately 20 participants per age group) in a parallel-group randomized controlled trial.

interventionParticipants were assigned using age-stratified randomization to a treatment or control group. Participants were categorized into three levels according to weekly physical activity measured by the Global Physical Activity Questionnaire and physical activity guidelines for adults. Each participant's grade was determined by applying equal weight adjustments for sex, age, and physical activity level, and the participants were assigned an exercise program corresponding to their grade. The exercise intervention consisted of a circuit training program alternating between aerobic and anaerobic exercises. The control group was instructed to maintain their usual physical activity levels.

main outcome measuresChanges from before to after exercise in clinical results (body composition, physical fitness, ultrasound-measured muscle/fat thickness, and biochemical data) were recorded during the 8-week exercise program and differences between pre- and post-exercise values of the groups were analyzed using the t-test and Wilcoxon rank-sum test.

resultsAmong 64 participants who had completed the program, 33 (51.5%) participated in the exercise program. The exercise program significantly increased abdominal muscle thickness (p < 0.01), reduced body fat percentage (p = 0.02) and waist circumference (p = 0.01), and positively affected various physical fitness indicators.

conclusionsThis study demonstrated the beneficial effects of a graded personalized exercise program on muscle thickness, body fat, and physical fitness and offers key data to support early preventive exercise programs in middle-aged adults to mitigate the risk of sarcopenia in later life.
