Mapping the NEI-VFQ-25 scores to the EQ-5D-Y-3L and CHU-9D utility values among adolescents with myopia.

The mean (SD) utility values were 0.962 (0.070) for the EQ-5D-Y-3L and 0.851 (0.160) for the CHU-9D.

The ordinary least squares and generalized linear model using stepwise-selected subscale scores demonstrated the best predictive performance for EQ-5D-Y-3 L (mean absolute error = 0.045, RMSE = 0.061, absolute error > 0.05 [%] = 30.37%) and CHU-9D (mean absolute error = 0.103, RMSE = 0.139, absolute error > 0.05 [%] = 61.50%), respectively.
