Association between the correction degree and Tinetti assessment score/VAS/KSS and association between the BMI and Tinetti assessment score. In each plot, the solid red line represents the smooth curve fit between the variables, while the blue bands represent the 95% confidence interval from the fit. a A threshold, nonlinear association between the correction degree and Tinetti assessment score was detected (P < 0.001) in a generalized additive model (GAM). Adjusted for age, gender; BMI, and leg. b A threshold, nonlinear association between BMI and Tinetti assessment score was detected (P < 0.001) in the GAM. Adjusted for age, gender, the correction degree, and leg. c A threshold, nonlinear association between the correction degree and VAS was detected (P < 0.001) in the GAM. Adjusted for age, gender, BMI, and leg. d A threshold, nonlinear association between the correction degree and KSS was detected (P < 0.001) in the GAM. Adjusted for age, gender, BMI, and leg.
