Mean and 95% CI of estimated mean change in walking outcome: Six-minute walk distance (6MWD, top) and the physical function component of the Medical Outcomes Study Short Form-36 (PF10, bottom) for each level of Patient Global Impression of Change (PGIC) category. Mean change per PGIC response catgory was estimated by a marginal model and generalized estimating equations clustered by participant with walking outcome as the dependent variable and categorical PGIC response as the independent variable. The model adjusted for site and month.
