and well-being by identifying individuals who are most likely to benefit from the intervention and least likely to experience harm. Eligibility requirements also minimize potential confounding factors that could obscure the treatment effect being investigated. Additionally, they help maximize the likelihood of observing a treatment effect by selecting participants who are more likely to respond to the intervention. Finally, eligibility criteria aid in the recruitment and retention of participants by clearly defining the target population for the
