How to compare two treatment protocols? research question

[makkhi]

Friends,

I want to compare two different treatment protocols for effective pain management. I'm going to follow up the patients at regular interval of time and compare the data.

So, what kind of study should I do?

prospective cohort study?
How should I choose the variables? There can be many, right?

Please help.
