Epidemiological Study on the Dose-Effect Association between Physical Activity Volume and Body Composition of the Elderly in China.
Article in International journal of environmental research and public health, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeThe purpose of this study was to investigate Chinese old adults' different body compositions in response to various levels of physical activity (PA). To the best of our knowledge, this is the first study to demonstrate the dose-response relationship between PA and body composition in old adults.
methods2664 participants older than 60 years (males:
resultsThe LBM and BM are significantly higher and the FM are significantly lower in old adults performing more PA volume than the WHO recommendation, compared with individuals performing less PA volume than the WHO recommendation. There were significant increases in LBM for males in "1-2 REC", "2-4 REC", and ">6 REC" groups, compared with the "0-1 REC" group; and there were significant increases in BM for males in "1-2 REC", "2-4 REC", compared with the "0-1 REC" group. The best PA volume for LBM and BM in females was the PA volume of "2-4 REC". Additionally, whether males or females, there was no significant difference in FM between the "0-1 REC" group and other separate groups.
conclusionThe PA volume that causes best benefit for body composition of the elderly occurs at 1 to 2 times the recommended minimum PA for males, while it occurs at 2 to 4 times that recommended for females. No additional harms for old adults' body composition occurs at six or more times the recommended minimum PA.
