If I want to adjusted my model by baseline age, do I need to add baseline age to all the follow up visits?
For example,
person visit group Age bloodpressure
1 baseline a baseline age 100
2 baseline b baseline age 101
1 visit1 a baseline age or visit1 age? 101
2 visit1 b baseline age or visit1 age? 102
Thank you very much!
