Power analysis and Statistical analysis
thromboembolic
COMPLICATION
Power analysis was performed by using GPower3.1.9.2. for outcomes of thromboembolic eventrate, overall complication rate, and local complication rate. Measurement data with a continuous normal distribution are expressed as the mean and standard deviation (SD), and Student’s t test was used. Continuous nonnormally distributed continuous measurement data are expressed as IQRs using the Mann‒Whitney U test. Count data were compared using the chi-square test. Repeated measures analysis of variance (ANOVA) was used to compare differences in hemoglobin and D-dimer levels. Data analysis was performed by using the SPSS statistical package (version 17.0), and P < 0.05 was considered statistically significant.
