Head-to-head comparison of health-state values derived by a probabilistic choice model and scores on a visual analogue scale

摘要

Health states were quantified based on discrete choice (DC) modeling and visual analogue scale (VAS) values using the five-level version of the EQ-5D (EQ-5D-5L). The aim of this study was to determine the extent of the relationship between DC derived values (indirect method) and VAS values (direct method).
