Efficacy and safety of treating chronic nonspecific low back pain with radial extracorporeal shock wave therapy (rESWT), rESWT combined with celecoxib and eperisone (C + E) or C + E alone: a prospective, randomized trial

Table 7 Absolute and relative numbers of patients in the different groups in this study who reached the different MCID scores of the OLBPDQ score as described in [48] (comparing data obtained at baseline with data obtained at 12 weeks post treatment)
