Table 4 Proportion of participants that reported changes equal to or greater than the minimal clinically important difference (MCID) for pain and function ratings. The MCID for the numeric pain rating scale (NPRS) was a 2-point change and for the foot and ankle ability measure (FAAM) was an 8-point change. Values are number of participants (%) that reached or surpassed the MCID threshold or relative risk (95% CI) of achieving the MCID with usual podiatric care plus physical therapy treatment (uPOD+PT) versus usual podiatric care (uPOD) for the intention-to-treat (ITT) and the per-protocol (PP) analyses
