We identified 35 children with SMPP complicated by PE, forming the PE group. A control group of 70 age\u2010 and sex\u2010matched children with SMPP without PE was randomly selected at a 1:2 ratio. Clinical, laboratory, and CT findings were compared between the groups. Least absolute shrinkage and selection operator (LASSO) and multivariate logistic regression were used to develop a scoring model using a nomogram. The model's performance was assessed via the receiver operating characteristic curve (ROC), fivefold cross\u2010validation, calibration curve, and clinical decision curve analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>LASSO regression and multivariate logistic regression analyses revealed that D\u2010dimer, neutrophil ratio, time to admission, pleural effusion, and necrotizing pneumonia were independent risk factors for PE in patients with SMPP. A nomogram prediction model was established based on the aforementioned independent risk factors. The area under ROC curve was 0.900. Fivefold cross\u2010validation results further confirmed the model's stability. The calibration curve revealed good agreement between the predicted and actual probabilities of PE caused by SMPP, and the decision curve demonstrated that the nomogram model had a higher clinical net benefit.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The nomogram serves as a predictive tool to aid in early intervention for pediatric patients with SMPP at high risk for PE, while minimizing unnecessary CTPA and overtreatment in low\u2010risk patients.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ppul.71046","type":"journal-article","created":{"date-parts":[[2025,3,19]],"date-time":"2025-03-19T13:32:43Z","timestamp":1742391163000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Development and Evaluation of a Nomogram for Predicting Pulmonary Embolism in Children With Severe <i>Mycoplasma pneumoniae<\/i> Pneumonia"],"prefix":"10.1002","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-6136-046X","authenticated-orcid":false,"given":"Yan","family":"Guan","sequence":"first","affiliation":[{"name":"Department of Radiology Children's Hospital of Shanxi Taiyuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Medical Imaging Shanxi Medical University Taiyuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Radiology Children's Hospital of Shanxi Taiyuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qing","family":"Hou","sequence":"additional","affiliation":[{"name":"Department of Radiology Shanxi Cancer Hospital Taiyuan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianfang","family":"Tong","sequence":"additional","affiliation":[{"name":"Siemens Healthineers Ltd.
