Subjects were randomly assigned to treatment with either captopril or valsartan and subsequently followed for 2 years. The primary endpoint was death from any cause. The study concluded that valsartan was as effective as captopril in patients who are at high risk for cardiac events after an MI. Which of the following describes this type of study?? A: Randomized controlled trial, B: Cohort study, C: Cross-sectional study, D: Case-control study, E: Crossover study,  <response>: This is a question about identifying the type of clinical study design based on the description provided. The key details are:- Patients were randomly assigned to receive either captopril or valsartan - They were then followed for 2 years to assess the primary outcome of death from any cause- The goal was to compare the effects of the two treatments on mortalityThis describes a randomized controlled trial, where patients are randomly allocated to different treatment arms and followed over time to assess outcomes. The randomization and comparison of treatments allows this design to determine cause-and-effect relationships.A: Randomized controlled trial
