Figure 7: Modulus measured at low stretch.

a) Evolution of low stretch modulus E₀ between cycles and between load-level series (n=5). b) Modulus at low stretch averaged over all series E₀ and all samples within a group. Error bar is standard deviation relative to inter-sample variability. * shows statistical significance between groups (n=5, p<0.05). The modulus measured at low stretch gives an assessment of elastic fiber network in term and preterm pregnant cervical samples.
