Linear regression test between ACD and difference in IOP (post – pre) for patients who underwent trabeculectomy with phacoemulsification

Variable	R2	B	P-value
Difference (IOP before)
IOP after 24 hours	0.006	−1.979	0.703
IOP after 7 days	0.017	−4.146	0.538
IOP after 15 days	0.050	−3.669	0.237
IOP after 30 days	0.084	3.884	0.181
IOP after 3 months	0.092	4.599	0.238
IOP after 6 months	0.061	−0.999	0.594
IOP after 12 months	0.147	1.486	0.396

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

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