The results of two way ANOVA (with the given signal parameter being the dependent variable and age and the subject group being the two independent variables).

Statistically significant differences satisfying the criterion of equality of variances are marked in bold font.
CG – control group; GODA – glaucoma suspects with glaucomatous optic disc appearance; POAG – primary open angle glaucoma; PACG – primary angle closure glaucoma; τ(ECG, BPL) – time delay between R wave peak of ECG and systolic BPL peak; τ(ECG, maxODP1) – time delay between R wave peak of ECG and the first major ODP maximum; τ(ECG, maxODP2) – time delay between R wave peak of ECG and the second major ODP maximum; τ(BPL, maxODP1) – time delay between systolic BPL peak and the first major ODP maximum; τ(BPL, maxODP2) – time delay between systolic BPL peak and the second major ODP maximum; preCT – preliminary crest time - time taken from minimum to the first major maximum of ODP shape; CT – crest time - time taken from minimum to maximum of ODP shape; HCT – time duration of heart cycle, taken from R peak to the next R peak of ECG shape; preRCT = preCT/HCT*100% – preliminary relative crest time; RCT = CT/HCT*100% – relative crest time and HR – the heart rate.

满足方差齐性准则的统计学显著性差异以粗体标注。CG：对照组（control group）；GODA：伴青光眼性视盘外观的青光眼疑似者（glaucoma suspects with glaucomatous optic disc appearance）；POAG：原发性开角型青光眼（primary open angle glaucoma）；PACG：原发性闭角型青光眼（primary angle closure glaucoma）；τ(ECG, BPL)：心电图（ECG, electrocardiogram）R波峰值与收缩期BPL峰值间的时间延迟（time delay between R wave peak of ECG and systolic BPL peak）；τ(ECG, maxODP1)：心电图R波峰值与首个主要ODP峰值间的时间延迟（time delay between R wave peak of ECG and the first major ODP maximum）；τ(ECG, maxODP2)：心电图R波峰值与第二个主要ODP峰值间的时间延迟（time delay between R wave peak of ECG and the second major ODP maximum）；τ(BPL, maxODP1)：收缩期BPL峰值与首个主要ODP峰值间的时间延迟（time delay between systolic BPL peak and the first major ODP maximum）；τ(BPL, maxODP2)：收缩期BPL峰值与第二个主要ODP峰值间的时间延迟（time delay between systolic BPL peak and the second major ODP maximum）；preCT：预波峰时间（preliminary crest time）——指从ODP波形最小值至首个主要峰值的时长；CT：波峰时间（crest time）——指从ODP波形最小值至峰值的时长；HCT：心动周期时长（heart cycle time）——取自心电图R波峰值至下一个R波峰值的时长；preRCT = preCT/HCT × 100%：预相对波峰时间（preliminary relative crest time）；RCT = CT/HCT × 100%：相对波峰时间（relative crest time）；HR：心率（heart rate）。
