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

objectivesThe purpose of this study is to explore the mediating effect of physical disability as well as the role of physical activity (PA) as a moderator in the relationship between physical frailty and health-related quality of life (HRQoL) among rural older adults in China.

designCross-sectional analysis.

settingRural households in Shandong of China (Rushan, Qufu, Laolin). PARTICIPANTS AND

methodsA survey was conducted among 3243 rural older adults. The data were collected using questionnaires measuring physical frailty, physical disability, HRQoL and PA. Bootstrap analyses were employed to explore the mediating effect of physical disability and also the moderating role of PA on physical frailty and HRQoL.

resultsAfter controlling for age and education, physical disability partially mediated the effect of physical frailty on HRQoL (indirect effect=-0.143, 95% CI -0.175 to -0.113), with the mediating effect accounting for 33.71% of the total effect. PA moderated the relationship between physical frailty and physical disability as well as the relationship between physical disability and HRQoL. Specifically, the interaction term between physical frailty and PA significantly predicted physical disability (β=-0.120, t=-7.058, p<0.001), and the interaction term between physical disability and PA also had a significant predictive effect on HRQoL (β=0.115, t=6.104, p<0.001).

conclusionsPA appears to moderate the indirect effect of physical disability on the association between physical frailty and HRQoL. This study provides support for potential mechanisms in the association between physical frailty and HRQoL. Encouraging rural older adults to increase PA appropriately might improve HRQoL for older adults with physical frailty and physical disability problems.
