Quizplus · Accepted Answer

Cohort studies are ideal for investigating the relationship between an exposure (cigarette smoking) and an outcome (weight gain) by following a group of individuals over time to observe any changes in health status. This type of study design allows for identification of cause-and-effect relationships and can control for confounding variables. Double-blind and single-blind studies are used to reduce bias in clinical trials, while conventional studies typically lack control groups or randomization.
