  1. This linear regression analysis used muscle strength change as a dependent factor. All the models were adjusted for baseline muscle strength. Additionally, confounders adjusting the model were aage, bgender, ccomorbidities change, dnon-steroidal anti-inflammatory drug change, ebody mass index change, fWestern Ontario and McMaster Universities Osteoarthritis pain change, gKellgren-Lawrence score change, and hphysical activity follow-up. Reduce patients numbers in the multivariate linear regression analyses due to random missing in the outcome measure or selected predictors. ESR, erythrocyte sedimentation rate; Ref., reference.
