Even though following people ahead for 3 years may seem like a prospective cohort, that is minor and the study design with randomly assigned experimental and control groups is still a randomized clinical trial
cbrelandTo add to this, a study would be observational, nothing is being assigned/added to the patients. This is too organized into groups/treatments to be a study +5

Cohort vs RCT
In cohort study, you don't assign the exposure, you just simply follow them (risk factors).
In RCT, "you assign the exposure" (drug, surgery)
