  1. SD standard deviation, WTD worse than death, 5L, EQ-5D-5L; 3L, EQ-5D-3L, 11111, best health state (no problems on each of the five dimensions: mobility, self-care, usual activities, pain/discomfort, anxiety/depression). For 3L, 1 represents no problems, 2 some problems, and 3 extreme problems/confined to bed. For 5L, 1 represents no problems, 2 slight problems, 3 moderate problems, 4 severe problems, and 5 extreme problems/unable to
