When determining the value of PRi at 7 or more, the risk of developing PE is regarded as high, with a PRi of less than 7, the risk of developing PE is regarded as low. ;EFFECT: method provides for timely stratification of pregnant women into a group for additional examination methods and preventive measures by evaluating the combination of the most significant indicators. ;1 cl, 3 dwg, 2 ex
