From the lowest (most favorable placebo response relative to treatment effect) to the highest (least favorable placebo response relative to treatment effect) were 0.30 (95% CI 0.16 to 0.43) for walking time/distance, 0.39 (95% CI 0.09 to 0.68) for muscle strength, 0.41 (95% CI 0.26 to 0.57) for PRO function, and 0.44 (95% 0.23 to 0.65) for PRO pain. (PRO, patient-reported outcomes; PRR, placebo response ratio; N.A, none available)
