Methods. aEuro integral One hundred and forty-seven asymptomatic women at high-risk of PTB were referred to specialist antenatal clinics and underwent CL and fFN testing over a 12-month period. Women had both tests undertaken between 22 aEuroS25 mm. With a known CL, the addition of positive fFN yielded significant hazard ratios regardless of CL (CL aEuroS > aEuroS25 mm-HR 2.78, CL aEuroS <a parts per thousand currency sign25 mm-HR 3.14, p aEuroS <0.05). The hazard ratios were insignificant when CL results were added to a known fFN. Conclusions. aEuro integral In high-risk asymptomatic women, fFN may be used as a primary screening tool with CL measurement being reserved for those with a positive fFN result. Further prospective studies are needed to confirm our findings.
