Individuals and sample size reason
A complete of 400 topics is going to be recruited for the RCT. According to an impact size of 0.3 (as reported in meta-analysis ), it is often determined that the test size for every combined team fabswingers sign up must certanly be 175 (for example. 350 as a whole) to realize 80% energy in detecting a between-group distinction using a separate t-test at a 0.05 importance degree. Presuming a projected 12.4% attrition rate (as reported in a RCT in a setting that is similar), an overall total of 400 subjects (i.e. 200 topics in each team) is essential.
