Figure 1. Average variable importance of MOAKS for predicting participant-reported pain; A, knee pain, aching, or stiffness on most days during the past 30 days. B, knee pain severity in past 30 days on a NRS. Subregion-specific scores that were ranked in the top 30 important variables (of 102 variables) for predicting pain at the time of incident ROA detection, as well as one and two years later, were highlighted for knee pain on most days (blue) and knee pain severity (orange). Asterisk(*) indicates scores that ranked in the top 30 for predicting both knee pain on most days during the past 30 days, as well as knee pain severity, at the time of incident ROA detection.
