Fig. 1From: Long-term participation in community-based group resistance exercises delays the transition from robustness to frailty in older adults: a retrospective cohort studySlopes of the changes and estimated marginal means (95% confidence interval) of the KCL scores of participants who performed community-dwelling group exercise. The slopes and estimated marginal means were based on results described in Table 2, obtained from the linear mixed models. The bar lines represent 95% confidence intervals for the estimated marginal means at each 5-year-age point. KCL, Kihon ChecklistBack to article page
