Study design: Prospective study in 14 pregnant women treated for threatened preterm labor.

As preventive strategies are largely ineffective, threatened preterm labor is a frequent problem that affects approximately 10 % of pregnancies.

Conclusion: In women with threatened preterm birth, quantitative fibronectin testing alone performs equal to the combination of cervical length and qualitative fibronectin.

Study design: We performed a model-based cost-effectiveness analysis to evaluate 7 test-treatment strategies in women with threatened preterm labor from a health care system perspective.

Study Design A secondary analysis of a randomized controlled trial on maintenance nifedipine includes women who remained undelivered after threatened preterm labor for 48 hours.

At present, there is evidence that tocolysis for 48 hours is useful in women with threatened preterm labour at least before 32 weeks.
