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
purposePhysical activity (PA) intensity remains a key determinant in managing chronic conditions. This study investigated how the proportion of moderate-to-vigorous physical activity (MVPA) relative to total volume is independently associated with cognitive function and depressive symptoms in middle-aged and older adults.
methodsA cross-sectional analysis was conducted utilizing data from 17,057 middle-aged and older adults in the China Health and Retirement Longitudinal Study. We used a Chinese version of the International Physical Activity Questionnaire to assess PA. Cognitive function and depressive symptoms were evaluated using the Telephone Interview for Cognitive Status and the Center of Epidemiologic Studies Depression Scale. The association between the proportion of MVPA to total PA volume and cognitive and mental health was tested using multivariable binary logistic regression analyses.
resultsThe findings indicated a suggested U-shaped pattern: 1%-33% MVPA was associated with the lowest odds of impairment particularly among older adults, for both cognitive function (adjusted odds ratio [aOR]: 0.48, 95% CI: 0.35, 0.67) and depressive symptoms (aOR: 0.57, 95% CI: 0.43, 0.76). Conversely, 67%-100% MVPA was associated with an increase in prevalence, particularly among male participants, where the favorable association with depression was no longer statistically significant (aOR: 1.01, 95% CI: 0.83, 1.22). Notably, adjusting for socioeconomic status unmasked significant favorable associations in middle-aged adults previously obscured by negative confounding.
conclusionThis study finds that MVPA is significantly linked to mental and cognitive health in older adults. Our findings identify a range associated with the lowest odds for MVPA proportion, specifically 1%-33% MVPA, that is associated with the lowest odds of impairment for cognitive impairment and depressive symptoms.
