Table 1.
Anti-C1q antibody concentrations in 60 women with failed pregnancies, including 30 women with ectopic pregnancy (EP) and missed abortion (MA) and 33 women with intrauterine pregnancy (IUP). The nonparametric Kruskal-Wallis test was used to identify differences among EP, MA, and viable IUP. To perform pairwise comparisons between groups Mann-Whitney test was conducted determining as critical value for significance P = 0.0167 after using Bonferroni correction which determined as critical value of significance for each (Mann-Whitney) test the value 0.0167. Therefore anti-C1q antibody levels are not helpful in differentiating between the three groups since as shown in Table 1 there is no P value <0.167.
