How accurate is a fetal fibronectin test

Objective: To determine the accuracy with which a cervicovaginal fetal fibronectin test predicts spontaneous preterm birth in women hint at or without symptoms of preterm occupation.

Design: Systematic quantitative examine of studies of test accuracy.

Data sources: Medline, Embase, Pa, Biosis, Cochrane Library, Medion, National Digging Register, SCISEARCH, conference papers, manual intent of bibliographies of known primary final review articles, and contact with experts and manufacturer.

Study selection: Two reviewers independently selected and extracted data on study characteristics, quality, elitist accuracy.

Data extraction: Preciseness data were used to form 2x2 contingency tables with spontaneous preterm dawn before 34 and 37 weeks' gravidity and birth within 7-10 days strip off testing (for symptomatic pregnant women) slightly reference standards. Data were pooled give produce summary receiver operating characteristic twistings and summary likelihood rati how accurate is a fetal fibronectin test
