According to Julious [83], a sample size of 12 per group is recommended for feasibility randomized clinical trials. A sample size of 20 per group, allowing for a conservative 20% dropout, would give us N = 16 total per group, which exceeded the threshold for a sufficiently precise estimate of variance in continuous variables to use in future studies. Furthermore, with N = 20 per group and 20% attrition, we were 80% powered to detect medium size effects (f = .25) between groups from baseline to follow-up on continuous variables of interest.
