Competing interests: Y.P. and K.W.K. are coauthors of three electroencephalography studies included in this review (references 17, 18, 19). To mitigate this potential conflict, risk-of-bias assessment and data verification for these studies were conducted independently by M.H. and S.Y.P., who had no authorship involvement in those studies, and K.W.K. was recused from adjudication related to them, as described in the “Methods” section. M.H. and S.Y.P. declare that they have no competing interests.
