*The DVI samples were found by a serologic survey of RhD-positive samples including weak D (southwestern Germany) and by molecular screenings of weak D samples (northern Germany and Tyrol). All DVI samples of the serologic survey were found in weak D as previously published.8
The observed distributions of the various DVI types in Tyrol and Southwestern Germany were statistically significantly different (P < .01, Brandt-Snedecor-χ2-test for 2 × 3 contingency tables with correction for multiple testing (n = 3) according to Bonferroni-Holm).
