Table 4 A comparison of patient reported outcome measures among groups at 12-months; Model 1: GLR describing the relationship of the no AE group to the reported group and the confirmed group. Model 2: GLR describing the relationship of the no AE group to the reported and confirmed group, when constrained to assume no difference between these two groups. Group 1: No AE group, Group 2: Reported group, Group 3: Confirmed group.
