Association Between the Changes in Physical Test Results and the Change in VISA-P Score
REGRESSION
The longitudinal changes in each physical test result are summarized in In the multivariable linear regression models, only a decreased VAS-SLS score was significantly associated with an increase in VISA-P score (β = −1.76; 95% CI, −3.09 to −0.43; The association between change in physical test results and clinical improvement. (A and B) The associations between the change in the Victorian Institute of Sports Assessment–Patella (ΔVISA-P) score and the change in the visual analog scale single-leg squat test (ΔVAS-SLS) score were evaluated by linear regression models using imputed and complete-case data, adjusted with study arms, sex, body mass index, age, and previous symptom duration, sports activity, and baseline VISA-P scores. Lines represent regression lines. Shaded areas represent the 95% CIs. The
