In contrast to the PPROM group, no correlations were found between cervical fluid and amniotic fluid progranulin levels (p = 0.11; p = 0.27; Fig. 3B), and cervical fluid progranulin and IL-6 levels (rho = 0.10, p = 0.28). The gene discussed is GRN; the disease is preterm premature rupture of the membranes.
