Compared to the LOP group, the EOP group had a higher proportion of women with severe preeclampsia (96.4% vs. 87.0%, p=0.0412), higher mean systolic (178 mmHg vs. 168 mmHg, p=0.005) and diastolic blood pressure (109 mmHg vs. 104 mmHg, p=0.026) on admission, as well as resistant hypertension (30.0% vs. 2.0%; p < 0.0001), placental abruption (16.8% vs. 4.0%, p=0.004), diagnosis of genitourinary infection (27.4% vs. 15%, p=0.0385), and the need for albumin transfusion (19.4% vs. 8.0%, p=0.019) (Table 4). The gene discussed is ALB; the disease is Hypertension resistant to conventional therapy.
