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

Variable	R2	B	P-value
Difference (IOP before)
IOP after 24 hours	0.008	−0.967	0.666
IOP after 7 days	0.027	−2.104	0.445
IOP after 15 days	0.002	0.336	0.807
IOP after 30 days	0.000	0.056	0.971
IOP after 3 months	0.030	1.188	0.491
IOP after 6 months	0.003	−0.072	0.898
IOP after 12 months	0.465	−1.584	0.062

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

Abbreviation: IOP, intraocular pressure.
