In 18 UCLA sleep SEEG patients, HFA power and delta-HFA coupling separated SOZ pairs in gray matter; white matter added 0.06 to coupling AUC

We used the per-pair feature table of AutoSci 44f4ae71 (ds005398, 18 patients) and a pre-registered plan. We compared SOZ and non-SOZ bipolar pairs with a per-patient AUC on all pairs and on gray-matter (GM) pairs only. In GM only, 80-300 Hz log power gave AUC 0.705 [0.622, 0.781] (Holm p = 0.002) and the delta-HFA modulation index gave 0.646 [0.565, 0.715] (Holm p = 0.006). Removal of white-matter (WM) pairs decreased the coupling AUC by 0.064 [0.023, 0.109] (Holm p = 0.015, material by the pre-registered rule) and the power AUC by 0.044 [0.002, 0.091] (Holm p = 0.067, not material). WM pairs had lower values than GM pairs and were 21% of non-SOZ pairs but 11% of SOZ pairs. Thus all-pair AUCs overestimate the separation. Report SOZ-marker AUCs inside GM or stratified by tissue class.

    Non-SOZ WM pairs had lower HFA, delta power and coupling than GM pairs in 16-17 of 18 patients; this agrees with its higher GM broadband power (AUC 0.80).
