Thank u, what would you say has a great positive predictive value for mortality within a year: 1. fev1 < 30%, 2. 6 minute walk test distance < 250m?

Q: thank u, what would you say has a great positive predictive value for mortality within a year: 1. fev1 < 30%, 2. 6 minute walk test distance < 250m?

Depends: If lung disease is advanced with no other significant comorbidities- FEV1 will probably predict best. If multiple comorbidities, including heart conditions, the walk test will probably predict better.
