Comparison of the relative power of four waves (delta, theta, alpha, and beta) of phase A1 (A), phase B1 (B), phase A2 (C), phase B2 (D), phase A3 (E), and phase B3 (F) of CAPs during sleep stage N3 without (solid bars) and with CPAP treatment (blanket bars). With CPAP, the relative power of delta waves was significantly increased in phase A1 (A), unchanged in phases A2 (C) and B2 (D), and significantly decreased in phases B1 (B), A3 (E), and B3 (F), that of theta waves was significantly increased in phases B1, A3 and B3, and that of other waves was either significantly decreased or unchanged. Values are shown as mean ± SEM. Paired t-tests. *P<0.05, **P<0.01.
