Computing EQ-5D-5L index values with SAS using the Germany (GER) Ludwig value set
Version 1.2 (Updated 31/01/2022)

The variables for the 5 dimensions of the EQ-5D-5L descriptive system should be named 'mobility', 'selfcare', 'activity', 'pain', and 'anxiety'. 
If they are given different names the syntax code below will not work properly. The 5 variables should contain the values for the different dimensions
in the EQ-5D health profile (i.e. 1, 2, 3, 4 or 5). The variable 'EQindex' contains the values of the 
EQ-5D-5L index values on the basis of the GER set of weights. 

You can copy and paste the syntax below directly into a SAS syntax window.
