  1. *This age-association is significantly associated with age in the test cohort, but not verified according to the requirements of the gatekeeper approach. Hypotheses were sequentially ordered for testing using a Gatekeeper strategy. A p value < 0.05 for the two-sided Wilcoxon rank-sum test statistic was considered significant.
