  1. Note. P value was calculated using logistic regression. Receiver operating characteristic (ROC) curves were generated to detect the cut-off value of sliding length for predicting the risk of non-union. AUC area under the curve
  2. *P < 0.05 was considered indicative of *statistical significance.
