SPSS statistical 20.0 software was used for data analysis. Continuous variables that followed a normal distribution are reported as the mean ± standard deviation (SD) and were compared using analysis of variance tests. The comparison of the success rate for one-time insertion of the Huber needle between Y-Z port and traditional Port was performed by Chi-square test. Variables that followed an abnormal distribution are reported as median [interquartile range (Q1, Q3)] and were compared using nonparametric tests. All hypothesis tests were two-sided, and p values < 0.05 were considered statistically significant.
