| The Chinese value set for the SF-6Dv2 was established using a time trade-off (TTO) approach, which will facilitate the calculation of quality-adjusted life-years. |
| A direct comparison between the TTO and discrete-choice experiment with a duration dimension (DCETTO) approaches indicated a good performance for both; however, minor issues of non-monotonicity existed in DCETTO estimates. |
| A systematic difference was found between value sets developed using the TTO and DCETTO approaches. |
