P values derived from Tukey’s pairwise comparisons, following two-way analysis of variance with significance level set to 5%. VN: vaginally nulliparous; VP: vaginally parous. YVN: younger vaginally nulliparous; YVP: younger vaginally nulliparous; OVN: older vaginally nulliparous; OVP: older vaginally parous.
