It perception remained significant (logistic regression: exp B = 0.495, p = 0.001) just after dealing with for ladies’ ages (exp B = 1.0, p = 0.71) and you can sociosexuality (exp B = step one.10, p = 0.46).

However, not surprisingly, we discovered that break up rate is lower should your girl try playing with OC throughout the mate possibilities ( contour step three a good): 237 regarding 1004 such as for example lovers (23.6%) had broke up, weighed against 497 out of 1491 lovers (33.3%) in which females just weren’t having fun with hormonal contraceptive (? 2 = , d.f. = step 1, p profile step three b; z = step 3.39, p = 0.001; average matchmaking size: sixty and you will 84 days for low-profiles and you can profiles, respectively). This difference is actually sturdy to exception to this rule out of outliers and you may tall beliefs (identified as countless anywhere between 1.5 and you will 3 x the fresh new inter-quartile range, or more than just three times new inter-quartile range), having median matchmaking period next being sixty and you can 81 days to possess non-users and you will OC pages, respectively (z = step three.fifty, p Effects of OC use in the course of partner choices into the relationship benefit.
