Inverse processing the PIGF data to predict the preeclampsia, when the area under the ROC curve (AUC) was 0.896 (0.863‐0.929), the sensitivity was 81.25%, the specificity was 98.51%, the positive predictive value was 95.1%, and the negative predictive value was 93.6%, the positive likelihood ratio was 54.5, the negative likelihood ratio was 0.19, and the Youden index was 0.797 when the cut‐off value was 90.8 ng/L. This evidence concerns the gene PIGF and preeclampsia.
