The objective of this study is to establish a prediction model of BPD-associated PH (BPD-PH) by integrating multiple predictive factors for infants with BPD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A retrospective investigation of the perinatal clinical records and data of echocardiography in all the preterm infants with BPD was performed from January 2012 to December 2019. A prediction model of BPD-PH was established based on the univariate and multivariate logistic regression analysis of the clinical data and evaluated by using the area under the receiver operating characteristic (ROC) curve (AUC), combined with the Hosmer\u2013Lemeshow (HL) test. Internal validation was performed with bootstrap resampling.<\/jats:p><\/jats:sec><jats:sec><jats:title>Result<\/jats:title><jats:p>A total of 268 infants with BPD were divided into the BPD-PH group and the no-PH group. Multivariate logistic regression analysis showed that the independent predictive factors of BPD-PH were moderate to severe BPD, small for gestational age, duration of hemodynamically significant patent ductus arteriosus \u2265 28 days, and early PH. A prediction model was established based on the \u03b2 coefficients of the four predictors. The area under the ROC curve of the prediction model was 0.930. The Hosmer\u2013Lemeshow test (<jats:italic>p<\/jats:italic> = 0.976) and the calibration curve showed good calibration.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The prediction model based on the four risk factors predicts the development of BPD-PH with high sensitivity and specificity and might help clinicians to make individualized interventions to minimize the
