Subjects were separated based on whether they had a positive venographic findings of PCS. Binary variables are summarized by percentage (95% confidence interval), while continuous variables are summarized as mean±standard deviation. Reported p values are the results of Fisher’s exact test for binary variables and unpaired t-tests for continuous variables. P-values controlling for age and BMI are results of logistic regression for each variable, with age and BMI as additional predictors. BMI: Body mass index, CT: Computed tomography, PCS: Pelvic congestion syndrome, IBS: Irritable bowel syndrome
