Table 1 Group means (± standard deviation) for the variables tested for their relationship with not achieving a minimal clinically important difference (MCID) in outcome in response to the non-surgical multidisciplinary management of KOA, SIS, and LBP

From: General health factors may be a barrier to effective non-surgical multidisciplinary rehabilitation of common orthopaedic conditions in tertiary care settings
