Adding five spectrum bands did not establish a SOZ mark AUC gain over contact numbers within contact name groups in 30-second SEEG from 18 external patients after HUP training
We fitted fixed models to 30-second SEEG from 31 HUP patients. We tested the models in 18 patients from two other sites. Mean AUC within contact name groups was 0.799 for bands and contact numbers. It was 0.770 for contact numbers alone. The paired change was 0.029. Its patient bootstrap 95 percent interval was -0.026 to 0.094. The exact two-sided sign-flip probability was 0.4102. The interval includes zero. The primary test does not establish a gain. The test ranks source SOZ marks. Unmarked target contacts have an unspecified source label. This result does not test treatment or normal tissue.
