Multiple correspondence analysis on intensity of elderly sports participation in China.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The background of aging has increased the demand of adaptability on elderly sports. In order to response to the aging society and achieve sports' health function for elderly participants, this research aim to clarify the elderly sport participants' characters and their potential influencing factors. Caused by too many variables in CHARLS, its cross-sectional nature precludes causal inference. The approach is purely exploratory. We obtained cases of 4982 elderly sports participants from the China Health and Retirement Longitudinal Study (CHARLS). They were divided into 3 clusters by cluster analysis, based on intensity of participation, and then figured out their potential influence by multiple correspondence analysis. Cluster 1 (47%) includes low-intensity participants. They only participate in mild exercise with low frequency. Cluster 2(32%) is non-high-intensity participants. They are deeply involved in moderate and low-intensity exercises with moderate frequency. Cluster 3 (21%) consists of multi-intensity participants. They are engaged in low-intensity, moderate-intensity, and high-intensity sports with high frequency. The intensity indicates that sport is an effective lifestyle for elderly individuals, particularly those who are villagers and not affluent. The urban-rural fringe area is associated with non-high-intensity participants in elderly sports. Additionally, marital statuses "never married" and "separated" are more associated with multi-intensity participants (Cluster 3). Institutionalized older adults living with a spouse show a higher likelihood of participating in high-intensity physical activities.
