Power calculation: Minimum Detectable Effect Size for Main Outcomes
|
Before
|
After
Each group in each study will consist of approximately 400 participants, for a total of about 4,000 participants across both studies. This sample size allows for the detection of an effect size of f² = 0.032 with 90% power at an alpha level of 0.01 in a linear regression with 8 predictors.
