Patients are booked for clinic follow-up Where, N = minimum number of subjects that need to be enrolled in the study to have a statistical power of 80% p 0 = proportion of sample with postoperative complications from a similar study, 4 10.9% p 1 = proportion of sample with postoperative complications from this study group, 76.5% q 0 = 1 − p 0 q 1 = 1 − p 1 α = probability of type I error, 0.05 β = probability of type II error, 0.02 z = critical value for a given α or β. Setting power at 80% (the minimum power), N = 128.…”
