Pearson Correlation Coefficients Between Shape Change, Displacement, and Change in Mean RNFL by Group

Group	A	B	C
OCT Parameter	Lumbar Puncture	CSF Shunt	Medical Treatment
Shape vs. Displacement	r = 0.66	r = 0.76	r = 0.87
	P < 0.001	P < 0.001	P < 0.001
Shape vs. RNFL	r = 0.15	r = 0.33	r = 0.44
	ns	ns	P < 0.01
Displacement vs. RNFL	r = 0.28	r = −0.23	r = 0.36
	ns	ns	P < 0.02

“RNFL” in this table refers to the change in mean RNFL thickness between pre and post intervention. “Shape” in this table represents the Procrustes distance between the pre and post intervention, that is, the change in shape. Procrustes distances were generated with GM software tpsSmall.²² Group B excludes three patients with optic atrophy at baseline. ns, not significant.
