From: The effect of air pulse-driven whole eye motion on the association between corneal hysteresis and glaucomatous visual field progression

	PGA usage group (65 eyes)	PGA non-usage group (43 eyes)	P value
age, years old	51.48 ± 9.6 [32.7 to 74.4]	57.58 ± 10.1 [37.4 to 79.0]	0.29
Mean GAT-IOP, mmHg	13.3 ± 2.1 [8.9 to 18.3]	13.7 ± 2.49 [9.4 to 20.2]	0.40
SD of GAT, mmHg	1.6 ± 0.43 [0.83 to 2.8]	1.5 ± 0.52 [0.79 to 3.6]	0.41
AL, mm	25.3 ± 1.4 [22.7 to 28.1]	24.9 ± 1.9 [22.3 to 29.2]	0.35
CCT, µm	532.6 ± 38.6 [458.3 to 624.3]	528 ± 31.5 [462.0 to 622.3]	0.23
Initial mTD, dB	−6.5 ± 5.5 [−20.0 to 0.52]	−4.5 ± 5.2 [−22.4 to 2.5]	0.030
mTD progression rate, dB/year	−0.23 ± 0.29 [−1.26 to 0.23]	−0.28 ± 0.36 [−1.8 to 0.27]	0.42
CH, mmHg	9.2 ± 1.1 [7.08 to 11.7]	9.1 ± 1.2 [6.5 to 11.8]	0.34
WEM-d, mm	0.30 ± 0.060 [0.16 to 0.44]	0.31 ± 0.085 [0.16 to 0.46]	0.66
WEM-t, ms	22.5 ± 0.78 [20.1 to 23.9]	22.3 ± 0.77 [20.0 to 23.9]	0.24

Values are shown as mean ± SE [range]. P values were obtained using the linear mixed model. AICc: corrected Akaike Information Criterion, SE: standard error, CST: CorvisST, WEM-d: maximum whole eye motion displacement, WEM-t: a time needed for maximum whole eye motion displacement, mTD: mean of total deviations, CCT: central corneal thickness, CH: corneal hysteresis, IOPcc: corneal compensated IOP, AL: axial length, GAT-IOP: Goldmann applanation tonometry-based intraocular pressure.
