Sleep. 1995 Jan;18(1):7-10.
Night-to-night variability in the minutes of slow-wave sleep (SWS: combined minutes of stages 3 and 4 sleep) was examined for 50 healthy adults: 23 women (56-82 years old) and 27 men (54-74 years old). Visually rated SWS was more variable night to night than computer-evaluated SWS using power spectral techniques. The night-to-night correlation of the visually rated SWS was 0.61. The night-to-night correlation of the spectrally evaluated SWS was 0.91.
对50名健康成年人（23名女性，年龄56 - 82岁；27名男性，年龄54 - 74岁）的慢波睡眠（SWS：3期和4期睡眠的总时长）的夜间变化情况进行了研究。与使用功率谱技术进行计算机评估的SWS相比，视觉评定的SWS在夜间的变化更大。视觉评定的SWS的夜间相关性为0.61。频谱评估的SWS的夜间相关性为0.91。
