Prediction Model Comparison Table—The table compares the AUC, accuracy, sensitivity and specificity of the typical HRV features and the presented features for different window sizes as well as the 95% confidence intervals for the AUC and accuracy values.

Asterisks indicate statistical significance at the α = 0.01 level. Bold indicates best score for that feature set. A non-parametric Mann-Whitney U test was used. The number of instances is denoted by n for each feature set.

星号代表在显著性水平α=0.01下具有统计学显著性。加粗字体表示对应特征集的最优得分。本次分析采用非参数曼-惠特尼U检验（Mann-Whitney U Test）。每个特征集的实例数以n标注。
