The sample size was generated from the data obtained from the retrospective analysis described above in B2. A two-sided test based on a normal distribution, a nominal significance level of 0.05, and a statistical power of 0.80 were assumed. Based on these assumptions, the power calculation reveals an equal sample size for both groups is calculated to be 41. Hence, the total sample size of 82 patients is required to detect statistically significant differences in the incidence of hypertriglyceridemia between infusion groups.
