Biomarkers in README.md Step3

[ApolloLSY]

Hi there,

Thanks for creating this package!
I was wondering why you use more biomarkers in README.md Step3 than you do in the phenoage_calc function body?


For example, I found that "lncreat_umol" and "uap" are not used in function phenoage_calc.

Could you please explain why these parameters are different? Thanks again!

The one in the bracket is the original phenoage value, which is saved in phenoage0.
