Fig. 2From: Does social participation decrease the risk of frailty? Impacts of diversity in frequency and types of social participation on frailty in middle-aged and older populationsSmoothing curves fitting for the dynamic changes in frailty scores across the 4 survey waves. A. Smoothing curves fitting for the change of mean frailty scores within different SP groups. B. Smoothing curves fitting for the change of mean frailty scores within different SP groups among respondents not frail at baseline. C. Smoothing curves fitting for the change of mean frailty scores within different SP groups among respondents frail at baseline. (0 = non-SP; 1 = occasional SP; 2 = weekly SP; 3 = daily SP. Smoothing curves were constructed based on general additive models, with all the covariates adjusted.)Back to article page
