Slopes of changes and estimated marginal means (95% confidence interval) of participants in community-dwelling group exercises. There were three panels: a weight-adjusted knee muscle strength; b timed up and go; c motor fitness scale. The slopes and estimated marginal means were obtained from linear mixed models. Bar lines show 95% confidence intervals for the estimated marginal means at each 5-year point. Figure 1 and Supplemental Table 1 correspond
