True or False? Confounding is not usually a major issue in cohort studies. True or False? A clinical trial is not a type of observational study design.
Understand the Problem
The question presents two statements related to research design: one about confounding in cohort studies and the other about clinical trials being observational studies. The task is to determine the truth value of each statement.
Answer
1. False, 2. True
- False, 2. True
Answer for screen readers
- False, 2. True
More Information
Cohort studies can have confounding issues as they do not control assignment of exposure like randomization in clinical trials does. Clinical trials are experimental studies, involving interventions deliberately imposed.
Tips
A common mistake is assuming that observational studies like cohort studies inherently control for confounding, which they do not.
