Figure 3.

Levels of CRH-BP and CRH-R2 mRNA in the studied groups irrespective of gestational age. Box and whisker plots represent mRNA levels of (A) CRH-BP in the cervical tissue (cx), (B) CRH-R2 in the cervical tissue (cx), (C) CRH-R2 in the isthmic biopsies (co) irrespective of gestational age. The studied groups are: in labor (Labor), which includes preterm and term in labor groups; not in labor group (not Lab), which includes preterm and term not in labor groups; non-pregnant group (NP). The number of samples analyzed in each group is shown under the group name. Statistically significant differences are indicated above the plots.
