Figure 1. Maternal serum PP13 concentrations.

Figure 1

(A) Log10 PP13 concentration increased as a function of gestational age in sera of normal pregnant women taken at routine prenatal care visits (n=46; ○ -·-) and in preterm and term controls taken at the time of delivery (n=18; ▿ –-–); however, did not correlate with gestational age in patients with preeclampsia with (n=11; ▲—) or without HELLP syndrome (n=12; ◆- -) at the time of delivery. (B) The regression line for log10 serum PP13 concentrations was different in the pooled group of controls (n=64; ◻- · -) from the pooled group of preeclampsia (●—). (C) Median maternal serum PP13 concentrations were significantly higher in women with preterm preeclampsia with or without HELLP syndrome than in preterm controls. Boxes represent the median±25th percentiles, whiskers the extreme values.
