Impact of age
There have been 23 women at ages between 23 and 35 years, and 37 at ages between 36 to 45 (table 1). Of the first group, 17 women had successful births (74 %), six had aborts (26 %), and two women did not get pregnant (9 %). Of the second group, 27 women gave births (73 %), 11 had aborts (30 %), and four did not get pregnant (11 %) (table 2).
A chi-square test was used to compare age groups and successful pregnancies under treatment with Anti-D. No expected cell frequencies were below 5, and the results showed no significant correlation with χ²(1) = 0·881, p(χ²) = 0·348, p(Fisher’s exact test) = 0·408, V = 0·121.
