Distribution of Hp phenotypes in the sample of preeclamptic women (PE) stratified by age of gestation at diagnosis.

	Hp 1.1; 𝑛=19	Hp 2.1; 𝑛=66	Hp 2.2; 𝑛=42	𝑃 value
≤34 weeks of gestation, 𝑛 (%)	6 (14.6)	23 (56.1)	12 (29.3)	0.791
>34 weeks of gestation, 𝑛 (%)	13 (15.1)	43 (50.0)	30 (34.9)

Chi-square test.
Preeclamptic women (PE) with diagnosis before 34 weeks of gestation (≤34 weeks of gestation) and after 34 weeks of gestation (>34 weeks of gestation).
