Question

Which method is used to study the following timeline?

• A. Cohort Study
• B. Cross sectional study
• C. Randomized Control Trials
• D. Interventional Studies

Answer 1

The Correct Option is A

To determine which method is suitable for studying the provided timeline, it's essential to evaluate the definition and applications of the given study methods:

• Cohort Study: This method tracks a group of people over a period to observe how certain variables may affect outcomes. It is often used to study the incidence and natural history of diseases or conditions.
• Cross Sectional Study: This approach observes a particular point in time, capturing a snapshot of a population's health and characteristics.
• Randomized Control Trials: A method that randomly assigns participants into groups to test the effect of a specific intervention.
• Interventional Studies: Involves actively intervening in a population to observe effects, often relating to trials.

Given the need to study a timeline which generally involves observation over a period, Cohort Study is the most fitting choice. This method effectively tracks changes over time and assesses how different factors contribute to outcomes.
