Minimal important change of the knee injury and osteoarthritis outcome score in patients with mild to moderate knee osteoarthritis – using three different anchor-based methods
MIC estimates for KOOS varied considerably by method. Predictive modeling yielded the most precise MIC estimates and should be considered for future research, particularly when the proportion of improved patients deviates from 50 %. These results also highlight the importance of methodological transparency for interpreting PROMs in non-surgical knee OA treatment.
