They were divided into a training set (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f179) and a validation set (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f77) using the random number table method. General information, clinical indicators, and serum levels of APN, Cys-C, and D-dimer of the patients were collected. In the training set, risk factors for placental abruption were screened through univariate analysis and multivariate logistic regression analysis, and a nomogram prediction model was constructed. The predictive efficacy of the model was evaluated by the receiver operating characteristic curve (ROC) and calibration curve, and then validated in the validation set. The clinical application value of the model was evaluated by decision curve analysis (DCA).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In the training set, 44 cases (24.93%) had placental abruption, while in the validation set, 19 cases (25.06%) did. There were no statistically significant differences in the incidence of placental abruption and clinical characteristics between the two groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;gt;\u202f0.05). Multivariate logistic regression analysis showed that decreased serum APN level, increased Cys-C and D-dimer levels, proteinuria quantification during pregnancy \u22655\u202fg\/24\u202fh, and oligohydramnios were independent risk factors for placental abruption in patients with severe pre-eclampsia (all\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05). The C-index of the constructed nomogram model in the training set and validation set was 0.809 and 0.730, respectively. The ROC curve showed that the area under the curves of the model for predicting placental abruption in the training set and validation set was 0.809 (95% CI: 0.722\u20130.896) and 0.730 (95% CI: 0.492\u20130.969), respectively, and the sensitivities and specificities were 0.588, 0.924, and 0.600, 0.840, respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n
