Impact of Anti-D dose
Of the 25 women who received Anti-D only after conception, 19 gave birth
(76 %), and 8 had aborts (32 %) (table 2). Of the 21 women who
received Anti-D prior to pregnancy, 14 gave birth (67 %), ten had
aborts (48 %). Six women did not get pregnant. For eight women full
data of Anti-D administration were not available (table 2).
In summary, the prophylactic administration of Anti-D also prior to
pregnancy does not appear to be more effective than the administration
only post gestation.
A chi-square test was used to compare pre and after conception
injections of Anti-D with successful pregnancies. No expected cell
frequencies were below 5. Results showed no significant correlation with
χ²(1) = 0·801, p(χ²) = 0·371, p(Fisher’s exact test) = 0·522, V = 0·132.
