I have a question regarding timepoints and analysis.

 

For example, lets say we have a data-set of 80 subjects with the following timepoints: baseline, 6 weeks, 6 months, 1 year and 2 years follow-up.

Two different studies on the same data needs to be performed. 

a) Study_1 with two timepoints (baseline and 6 weeks)

b) Study_2 with all time timepoints (baseline, 6 weeks, 6 months, 1 year and 2 years follow-up).

As i understand, the more time points the better the [BASE] you will get. The BASE is going to be edited

Therefore, even though Study_1 only is going to be using two timepoints, do you still recommend to include all the 5 time points in creating the [BASE] even though only 2 time points will be used?

Best regards,
