Table 3.

Characteristics of patients in the train and test sets and p-values from comparison of distributions. A p-value of <0.05 signifies a significant difference between both sets.

Baseline Characteristics	Train Set	Test Set	p-value
Age (years)	72	71	<0.01
MD (dB)	−3.77	−3.64	0.09
IOP (mmHg)	15.2	15.4	0.25
CCT (μm)	537	539	0.46
CDR	0.64	0.65	0.57
MD slope (dB/year, non-progressors)	+0.68	+0.67	0.11
MD slope (dB/year, progressors)	−0.97	−0.96	0.42

IOP = Intraocular Pressure, CCT = Central Corneal Thickness, CDR = Cup-to-disc Ratio, MD = Mean Deviation (dB).
