What are Some Common Alternatives in Study Designs?
1. Case-Control Studies: These are observational studies that compare individuals with a specific condition (cases) to those without (controls). They are particularly useful for studying rare diseases.
2. Cohort Studies: These studies follow groups of people over a period to see how different exposures affect outcomes. They can be prospective or retrospective.
3. Randomized Controlled Trials (RCTs): These are considered the gold standard for determining causality. Participants are randomly assigned to intervention or control groups to eliminate bias.
