3. Figure 2
Associations between predicted probabilities of 1-year worsening symptoms and daily physical activity by Kellgren–Lawrence grades. Predicted probabilities of 1-year worsening symptoms were estimated using nonparametric logistic models adjusted for covariates listed in Tables 3 and 4. Solid line represents estimated probabilities from nonparametric logistic models; shaded areas indicate 95% confidence bands for the estimates.
