The sample size was determined to obtain 90% power to detect a 20 percent difference in between the 2 groups, as this difference is considered to be clinically significant. In accordance with previous studies (26-31), the investigators hypothesized that the occurrence of the primary endpoint will be at 35% in the control group. With the threshold for statistical significance set at a p-value of 0.05 (two-sided alpha), these calculations showed that 166 patients are needed (83 per group). Assuming that potentially 15% of patients will be lost to follow-up, a total of 190 individuals need to be included.
