Inclusion criteria are crucial for several reasons:
1. Homogeneity: They help create a homogenous study population, which reduces variability and enhances the ability to detect a true effect. 2. Generalizability: Properly defined criteria ensure that the results can be generalized to the broader population. 3. Safety: They protect participants by excluding those who may be at higher risk of adverse events. 4. Efficiency: Well-defined criteria streamline the recruitment process, making it faster and more cost-effective.
