Correlation between Wells score and incidence of DVT with coefficient of determination (R ² = 0.88, p = 0.0016) demonstrating a strong linear correlation. a Receiver operating characteristic (ROC) curve demonstrating the performance of Wells score in predicting likelihood of DVT. b Area under the ROC curve (AUROCC) value shows that high Wells scoring system is efficient in identifying the patients at risk for developing DVT based on their estimated probability after trauma
