Comparison of the COVID-19 and reference groups
In the COVID-19 group, 44 out of 231 (19.0%) cases were identified to
be at a high risk for PE at the first-trimester screening, and this
incidence was significantly higher than the 1,719 out of 13,033 (13.2%)
found in the general population (p=0.012). When PE risk factors were
examined individually, we found that women with COVID-19 had higher
UtAPI and body mass index (BMI), higher incidence of chronic
hypertension, and fewer were smokers. No significant differences were
found in MAP, PlGF, maternal age, black race, or history of PE or
diabetes mellitus between the COVID-19 group and the general population
(Table 1).
