Δ, difference compared to baseline. Coefficient (i.e. mean changes associated with the index variable) and p values are reported. Reference subject: Female, KL grade 1. Intercept indicated the mean change for a reference subject. Values represent absolute adjusted change in score due to 1 unit increase (continuous variable) or absolute variation with respect to the reference category (Gender, KL grade)
M male, KL Kellgren-Lawrence
