Mean values (± standard deviation) for sleep and demographic variables across sleep cluster groups and controls.

Sleep onset and offset are time values in decimal form; TST = total sleep time (minutes); WASO = wake after sleep onset (minutes); Ctl = controls; ANOVA = analysis of variance; (D/B/A) = depression/anxiety/bipolar; HDRS = Hamilton Depression Rating Scale (not including insomnia items); SOFAS = Social and Occupational Functioning Scalea- Welch statistic used due to significantly unequal variance between groupsMean values (± standard deviation) for sleep and demographic variables across sleep cluster groups and controls.睡眠起始与睡眠终止为十进制格式的时间数值；TST为总睡眠时间（分钟）；WASO为睡眠起始后觉醒时长（分钟）；Ctl为对照组；ANOVA为方差分析（Analysis of Variance）；(D/B/A)为抑郁/焦虑/双相障碍组；HDRS为汉密尔顿抑郁量表（Hamilton Depression Rating Scale，不含失眠相关条目）；SOFAS为社会与职业功能评定量表（Social and Occupational Functioning Scale）。由于各组间方差存在显著不齐，故采用韦尔奇统计量（Welch statistic）。以下为睡眠聚类组与对照组在睡眠及人口统计学变量上的平均值（±标准差）。
