In the female subsample, the effects of DDSS and age were both highly significant (Q = 14.7; p = 0.0002, Q = 23.8; p < 0.0001, respectively), but the effect of DDSS on usability ratings was different for younger patients than it was for older participants (Q = 7.9; p = 0.005), suggesting that younger women (<52 years) showed greater usability rating differences between Ada and Rheport.
