Lasso regression analysis results
We screened out the variables using the offspring outcome of fetal
distress by lasso regression analysis. Six optimal variates were
selected from the twenty-one variables as follows: age, gestational
week, delivery method, placenta previa, abnormal cord blood flow (absent
or upside down), LMWH (Figure 1B and C). Table1 lists the patients’
characteristics of the Chinese population among the six independent
predictors. According to the outcome of admission to NICU, nine optimal
variates were screened out among the twenty-one variables using lasso
regression analysis, for instance pregnancy times, gestational week,
delivery method, HDP, ICP, oligohydramnios, RSA, using prednisone,
newborn sex (Figure 1D and E). Table2 lists the information of nine
variables.
