Comparison of baseline characteristics between patients with Congenital Bilateral Aplasia of the Vas Deferens (CBAVD, n = 42) and obstructive azoospermia without CBAVD (No-CBAVD-OA, n = 112)
Continuous variables were presented as medians (first quartile-third quartile) and compared using the Mann–Whitney U rank-sum test
Categorical variables were presented as % (n/N) and compared using the chi-squared test
P value < 0.05 was considered statistically significant
