Prognostic Value of Baseline Physical Results
INTERACTION
There was a significant increase in VISA-P score in the whole group, with an increase of 23 points (95% CI, 19-28 points; Bonferroni-corrected Prognostic Mixed-Effect Model of Baseline Physical Test Results for VISA-P ImprovementLRT, likelihood ratio statistic; VAS, visual analog scale; VAS-palpation, VAS by palpation test; VAS-SLS, VAS after single-leg squat test; VAS-3-jumps, VAS after 3 jump trials; VISA-P, Victorian Institute of Sports Assessment–Patella.Interaction terms (time × each physical test result) were tested using the likelihood ratio test, representing the effect of the physical test results on the VISA-P score over time.The effect of the physical test results from models without the time × physical test interaction.These (A-J) Visualization of the prognostic value of baseline physical test results. The prognostic value of each baseline physical test result on the progression of the Victorian Institute of Sports Assessment–Patella (VISA-P) score (0-100 points) over 24 weeks is depicted by dichotomizing baseline physical test results into low and high levels using the median value for illustration purposes. Plots represent the progression of VISA-P scores over 24 weeks by different levels of baseline physical test results. Dots represent marginal estimated means by mixed-effect model without time × physical test interaction. Shaded areas represent the 95% CIs after the Bonferroni correction. There was not a significant difference in the rate of increase in VISA-P between low and high baseline physical test results.
