(a) The ROC curve reflects the relationship between the true positive rate (sensitivity) and false positive rate (1-specificity). The area beneath the ROC curve reflects the likelihood of causing nonunion of LT. According to the ROC curve in our study, the area under the ROC curve was 0.933. After comprehensive consideration of sensitivity and specificity, we defined 0.35 as the critical value. (b) The distribution and cumulative curve of displacement ratios. *, ** and *** mean P < 0.05, P < 0.005 and P < 0.001 respectively. RD: Ratio of Displacement
