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
backgroundGiven that limited research has examined the relationships between lifestyle activities of varying intensities, including moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and sedentary behavior (SB), and dynapenia, which refers to an age-related decline in muscle function, this study aimed to investigate the longitudinal associations between MVPA, LPA, and SB and the risk of dynapenia among older adults in Taiwan.
methodsThis longitudinal study included older adults aged ≥ 65 years with independent mobility, recruited from the National Taiwan University Hospital. Baseline data were collected from September 2020 to December 2021 and follow-up data were collected until December 2022. Participants wore a tri-axial accelerometer (GT3X + ActiGraph) on the hip for seven consecutive days to evaluate baseline time spent of MVPA (≥ 2020 counts/min), LPA (100-2019 counts/min), and SB (< 100 counts/min). To confirm the dynapenia classification at baseline and follow-up, participants underwent standard assessments, including handgrip dynamometry for muscle strength, bioelectrical impedance analysis for muscle mass, and a 6-m walk test for physical performance. Adjusted binary logistic regression analyses were conducted to examine the association between lifestyle activities and dynapenia risks.
resultsAmong 154 participants (mean age 80.3 ± 7.2 years; 53.9% women), 53.9% were classified as having dynapenia at baseline, compared to 55.2% at follow-up. Participants spent an average of 16.9 (± 26.6) min in MVPA, 249.5 (± 85.7) min in LPA, and 604.5 (± 76.4) min in SB daily. The longitudinal analysis results indicated that higher MVPA time was significantly associated with lower odds of dynapenia in both the unadjusted (odds ratio [OR] = 0.625, 95% confidence interval [CI]: 0.466-0.837) and fully adjusted models (OR = 0.578, 95% CI: 0.406-0.823). Each additional 10 min/day of MVPA was associated with 42.2% lower odds of dynapenia in the adjusted model. No significant prospective associations were observed between the LPA or SB time and dynapenia.
conclusionThis study provides longitudinal evidence that higher MVPA levels are significantly associated with a reduced dynapenia risks among community-dwelling older adults in Taiwan. These findings underscore the importance of promoting MVPA as a part of lifestyle interventions aimed at preserving muscle function and preventing dynapenia in older populations.
