Health-related Quality of Life
All total scores and subscales of RAND-36 significantly improved in both when com- paring BL with 15M and BL with 24M (p<0.001 in all, Table 2). RAND-36 scores of all scales at 15M were significantly higher (p<0.05 in all) than at 24M. IWQOL-lite scores also improved significantly in all scales, when comparing BL with both follow-up mo- ments (p<0.001 in all, Table 2). IWQOL-lite scores at 24M follow-up were lower than at 15M, this difference was not statistically significant.
