data 5dThe new storage medium, also referred to as 5D memory crystal, uses ultrafast laser technology to encode data into multiple layers of glass, achieving densitiesEQ-5D-5L utility index, and the domain of physical function and pain with the SF-6D utility index. Ceiling effect of EQ-5D-5L (59%) is greater than SF-6D (22.4%). The Bland and Altman plot
