“…Baseline Characteristics and Technical Outcomes Values are presented as mean ± SD for continuous variables and frequencies for categorical variables with percentages in parentheses. The definition of the dominant tumor location is shown in Figure 1a-c. OAE ¼ ovarian artery embolization; UFS-QOL ¼ Uterine Fibroid Symptom and Quality of Life.total leiomyoma volume per case, the sample size of cases was estimated to be 14 with R software (R Foundation for Statistical Computing, Vienna, Austria) under the following conditions: calculated sample size for the hypothesized value r, 0.90; null hypothesis r0, 0.60; number of ratings, 2; desired a, .05; number of tails, 2; desired power, .80(22,23).Reader 2 independently interpreted data in a blind manner and measured the number of tumors, uterine volumes, and infarction rates of total leiomyoma volume using 14 randomly selected cases. Regarding individual leiomyomas in all cases, the sample size of tumors was estimated to be 49 with the same software under the following conditions: calculated sample size for the hypothesized value r, 0.80; null hypothesis r0, 0.60; number of ratings, 2; desired a, .05; number of tails, 2; desired power, .80(22,23).…”
