‡Statistical test methods: Fisher’s exact test for categorical data, Student’s t-test or Wilcoxon rank sum test for continuous data. *Age and duration of rest are values at the time of US and other data are values at the registration. †Catheterization was investigated regardless purpose and site. Values are expressed as mean ± standard deviation for continuous variables. DVT: deep vein thrombosis; BMI: body mass index
