Predictive Factors and Nomogram for Malignant Pulmonary Nodules (≤ 1 cm).

Key Points

• To identify independent predictors of malignancy in pulmonary nodules that are 1 cm or smaller and develop a nomogram for clinical prediction.
• Analyzed characteristics of nodules including density, diameter, and calcification status.
• Created a nomogram incorporating clinical and computed tomography features.
• Evaluated the nomogram's predictive performance.
• Nodule density, diameter, and calcification status are key predictors of malignancy.
• The nomogram demonstrates good predictive performance but requires further external validation.
