From: An international comparison of deceased and living organ donation/transplant rates in opt-in and opt-out systems: a panel study

  1. *This estimate is based on Pearson Chi-Squared. Given the low number of opt-out and common law countries the Yate’s continuity correction (χ 2(1) = 6.96, P = .008) or Fisher’s Exact Test (P = .004, two-tailed) were applied. Both were significant.
