What was measured
The EQ-5D-3L VAS measures a patient's self-rated current health state using a visual analogue scale measured on a 20-cm scale with 10-point intervals. Scores range from 0 at the bottom of the scale, representing the worst imaginable health state, to 100 at the top of the scale, representing the best imaginable health state. The change score was calculated as the postbaseline value minus the baseline value. A negative change reflects decline at the postbaseline timepoint and a positive change reflects improvement at the postbaseline timepoint.
Analysis population: Eligible participants enrolled to the quality of life (QOL) substudy who received protocol treatment and had outcome measure data at baseline and at least one postbaseline timepoint.
Groups in this outcome
