AI Article Synopsis
- * It analyzed 1557 cases with confirmed diagnoses through fine-needle aspiration, identifying 8 key predictors of malignancy through statistical methods.
- * The nomogram outperformed the existing ACR score model in predictive accuracy, showing it can be effectively applied in clinical settings to assess cancer risk in thyroid nodules.
Article Abstract
Objectives: The objective of this study was to develop and validate a nomogram model integrating clinical, biochemical and ultrasound features to predict the malignancy rates of Thyroid Imaging Reporting and Data System 4 (TR4) thyroid nodules.
Methods: A total of 1557 cases with confirmed pathological diagnoses via fine-needle aspiration (FNA) were retrospectively included. Univariate and multivariate logistic regression analyses were conducted to identify independent predictors of malignancy. These predictors were incorporated into the nomogram model, and its predictive performance was evaluated using receiver-operating characteristic curve (AUC), calibration plots, net reclassification improvement (NRI), integrated discrimination improvement (IDI) and decision curve analysis (DCA).
Results: Eight out of 22 variables-age, margin, extrathyroidal extension, halo, calcification, suspicious lymph node metastasis, aspect ratio and thyroid peroxidase antibody-were identified as independent predictors of malignancy. The calibration curve demonstrated excellent performance, and DCA indicated favourable clinical utility. Additionally, our nomogram exhibited superior predictive ability compared to the current American College of Radiology (ACR) score model, as indicated by higher AUC, NRI, IDI, negative likelihood ratio (NLR) and positive likelihood ratio (PLR) values.
Conclusions: The developed nomogram model effectively predicts the malignancy rate of TR4 thyroid nodules, demonstrating promising clinical applicability.

Objective: To develop and validate an individualized nomogram for predicting adnexal torsion in women with abdominal pain and an adnexal mass based on preoperative non-contrast computed tomography (CT) findings.
Methods: This retrospective study included 200 women with surgically resected ovarian lesions who underwent preoperative non-contrast CT for abdominal pain from January 2017 to September 2023 in seven hospitals. The 200 patients were randomly divided into a development group (140 cases) and a validation group (60 cases).

Background: In China, 80% of Hepatocellular Carcinoma (HCC) is associated with cirrhosis. Portal hypertension, the most common outcome of cirrhosis progression, has a high incidence. Platelet count/spleen diameter ratio (PSL) with a cut-off value of 909 can predict the presence of esophagogastric varices and thus portal hypertension, which is also an independent risk factor for early recurrence and late recurrence of hepatocellular carcinoma after resection.
