*Non-parametric test for trend across ordered groups developed by Cuzick [47]. We used this to test for differences between 6 and 12 months in responses for each EQ-5D-3L item
**At 12 months, 224 participants self-reported the EQ-5D-3L in full; 19 provided no response to 3L; 13 had 3L proxy reported by next of kin
