Comparisons of absolute (A) and relative power (B) of NCAP, absolute (C) and relative (D) power of delta waves in two types amplitude of NCAP during sleep stage N3 without (blanket bar) and with CPAP treatment (grey bar). Note that the absolute and relative powers of delta waves with an amplitude ≥75 μV, not <75 μV in NCAP were significantly increased with CPAP treatment although those of overall delta waves were not significantly changed. Values are expressed as median (minimum-maximum). Wilcoxon paired signed rank test, *P<0.05, **P<0.01.
