A similar analysis was conducted for responder rate (one-point drop) on the numeric rating scale demonstrating a marginally significant effect for sessions x duration ( F (4,93) = 2.08, p = 0.089), indicating a trend that more people respond to 6 sessions of 20 minutes than to 6 sessions of 30 minutes ( t = 2.55, p = 0.024) (see Fig. 3 ).
