Long-term Study on the Statistical Properties of Uterine and Umbilical Arterial Resistance Indexes by Simple Doppler Velocimetry in Patients with Perinatal Prognosis Stratification: Part II

In this report a new wayof compute the total arterial uterine resistance index is presented, and how the Friedman-Anova rank test is utilized to search the probable statistical difference for the corresponding arterial resistance indexes among patients.Also, the nonlinear regression byexponential growth adjustment isused to describe the statistical variabilty of patients'data. The total results obtained in this project support the beneficial approach of a long-term observational studyand reveal a characteristic profile followed by three patients with very different perinatal prognosis as seen by the variability of statistical properties.
