Table 2:
Pre-operative and post-operative prediction results in terms of accuracy (mean and 95% CI) for each test individually and different classifiers: Logistic regression (first row), linear SVM (second row), and non-linear SVM (third row). The best accuracy values for pre-operative and post-operative are shown in bold.
