Prediction model Construction
Selecting six optimal variates about fetal distress risk were analyzed by multivariable logistic regression analysis. The results were given in Table 3, the prediction model that merged the above six independent predictors was presented using the nomogram (Figure 2A). Selecting nine optimal variates about the risk of admission to NICU were performed by multivariable logistic regression analysis. The results listed in Table4. The prediction model that amalgamated the above four independent predictors was revealed as the nomogram (Figure 2B).
