Linear regression test between ACD and IOP difference (post – pre) in eyes that were subjected to phacoemulsification

Variable	R2	B	P-value
Difference (IOP before)
IOP after 24 hours	0.565	−4.184	0.001a
IOP after 7 days	0.163	−1.654	0.370
IOP after 15 days	0.098	−2.501	0.072
IOP after 30 days	0.000	0.057	0.963
IOP after 3 months	0.006	0.618	0.718
IOP after 6 months	0.061	1.592	0.324
IOP after 12 months	0.126	2.813	0.213

Note: R²= coefficient of determination, B = slope of the line, P = statistical significance,

^asignificant P<0.05.

Abbreviations: ACD, anterior chamber depth; IOP, intraocular pressure.
