Prediction of preterm delivery < 34 weeks. Boxplot analysis of maternal serum PlGF (A) and sFLT-1 (B) levels and their ratio (C). Patients with delivery at <34 weeks of gestation (n = 6) were compared with the remaining patients (n = 44). Boxes show the median (black line), and 25th and 75th percentiles (top and bottom lines of the box). The lines outside the box represent minimum and maximum values. Circles are outliers (>1.5× from the interquartile range). P values were computed by Mann–Whitney statistical tests.
