  1. Confidence intervals were obtained via bias-corrected, accelerated bootstrap with 10,000 repetitions. The different age groups among the types of hernias were compared by van der Waerden’s test as the omnibus-test followed by groupwise comparisons via the Conover-Iman test with correction for multiple comparisons using the method of Benjamini-Hochberg
  2. M male, F female, CI confidence interval
