By unpaired AUC analysis, the full Brock (AUC, 0.84; 95% confidence interval [95% CI], 0.81–0.86) and Mayo (AUC, 0.82; 95% CI, 0.79–0.85) models had similar accuracy (P = 0.41), as did the full and parsimonious (AUC, 0.83; 95% CI, 0.80–0.86) Brock models (P = 0.79), but the VA model (AUC, 0.77; 95% CI, 0.73–0.80) was less accurate than the full Brock model (P = 0.003). Objectives: Clinical prediction models assess the likelihood of malignancy in pulmonary nodules detected by computed tomography (CT). patients who are being investigated for lung cancer. As such, emphysema confers increased risk for lung cancer in smokers (4) and in adults with a solitary pulmonary nodule (e.g., Brock University cancer prediction equation). This study aimed to validate four such models in a UK population of patients with pulmonary nodules.
