最近学看论文，看不懂它用的统计学方法。原文统计学设计及图表如下：

Screening accuracy was assessed by constructing receiver–operating characteristics (ROC) curves for UtA mean, lower and higher RI in the prediction of early, preterm, late and term PE. The area under the curve was calculated and an ANOVA test was performed to identify differences in performance of sensitivity rate.

下划线说的利用方差分析方法比较三种因素（UtA mean, lower and higher RI值，均为计量数据 ）对某种结局（PE）预测的敏感性进行比较。表图如下

在此我想请教其统计方法的使用合理吗？合理的话在SPSS里如何实现使用ANOVA来比较不同敏感性？

谢谢！
