eq5d paretian classification of change

[Rose Matthews]

I've been trying to calculate eq5d paretian classification of change
I have not used the eq5d community generated command, however instead used the Stata syntax available from here:
https://euroqol.org/wp-content/uploa...eset_STATA.txt

and replaced with the EQ5D 5L value sets available from

https://link.springer.com/content/pd...018-0628-3.pdf

I am now trying to calculate the Paretian classification of health change .
DOes anyone have any experience calculating this, I;ve had a look at the text here (pG 10)

'Denoting ‘better than’ as > and ‘worse than’ as y and y>z then x>z and if x 12122'

I don't clearly understand what they mean....
Would anyone be kind enough to check the bold section of my code of my interpretation of what constitutes -better- worse- same
I think there may be something wrong as my paretian ==4 I had no changes...

gen eq_mobility_d=eq_mobility_post-eq_mobility_pre
gen eq_selfcare_d=eq_selfcare_post-eq_selfcare_pre
gen eq_activity_d=eq_activity_post-eq_activity_pre
gen eq_discomfort_d=eq_discomfort_post-eq_discomfort_pre
gen eq_anxiety_d=eq_anxiety_post-eq_anxiety_pre

gen eq_total_d=eq_mobility_d + eq_selfcare_d + eq_anxiety_d + eq_discomfort_d + eq_activity_d

////Or should this be >0 ?
gen eq_total_better=0
replace eq_total_better=1 if eq_total_d<0

gen eq_total_worse=0
replace eq_total_worse=1 if eq_total_d>0

gen eq_total_same=0
replace eq_total_same=1 if eq_mobility_d==0 & eq_selfcare_d==0 & eq_anxiety_d==0 & eq_discomfort_d==0  & eq_activity_d==0

gen eq_total_noncomp=0
replace eq_total_noncomp=1 if eq_total_d==0 & eq_total_same==0


gen eq_paretian=0
replace eq_paretian=1 if eq_total_better==1
replace eq_paretian=2 if eq_total_worse==1
replace eq_paretian=3 if eq_total_same==1
replace eq_paretian=4 if eq_total_noncomp==1
