Table 2.
Area under the receiver operating characteristic curve (AUC) for the nodal status predictions of the model N-LVI_presentI for different strategies for imputing values of lymphovascular invasion (LVI) status. The highest AUC, except when using the original LVI values, was obtained when imputing LVI status using the probabilistic imputation, this is why we chose to use this method for LVI imputation in the subsequent analysis.

Original LVI status | LVI status imputed by the predicted probability | LVI status imputed by probabilistically categorical imputation | LVI status imputed by categorical imputation with threshold 0.3 |
| N-LVI_presentI, AUC (95% CI) | 0.750 (0.704-0.795) | 0.737 (0.689-0.783) | 0.740 (0.693-0.784) | 0.738 (0.691-0.783) |
