Maternal Serum Angiogenic Factor sFlt-1 to PlGF Ratio in Preeclampsia: A Useful Marker for Differential Diagnosis and Prognosis Evaluation in Chinese Women

Figure 3

Correlation between sFlt-1/PlGF ratio and time of delivery in PE patients. Box-whisker plots displayed the logarithmic distribution of the sFlt-1/PlGF ratio in two subgroups of PE patients: delivered within 7 d () and longer than 7 d () from the time enrolled in the hospital. Boxes indicate interquartile range; whisker indicates range; error bars indicate median. ○ means mild outliers. means extreme outliers. The sFlt-1/PlGF ratio of 301.0 was drawn into the graph as a solid line. The sFlt-1/PlGF ratio in the subgroup delivered within 7 d was significantly higher than the subgroup delivered longer than 7 d ().
