Construction and application of model for the choice of NVBG procedures
To determine which NVBG procedure should be chosen, we constructed predictive models for the choice of NVBG procedures. Of the 128 hips that underwent successful NVBG, they were divided into a new training cohort (n = 92) and a validation cohort (n = 36) at a ratio of 7:3 to ensure that there was no overlap of hips in the two datasets. Radiomics features and clinical predictors were extracted from patients, with the choice of NVBG procedures used as the dependent variable. The predictive models were then constructed and validated, with the optimal model visually quantified to assist in clinical procedure selection.
