A Possible Regression Equation for Predicting Visual Outcomes after Surgical Repair of Open Globe Injuries

Table 4

The significant independent variables after the backward stepwise elimination.

Independent variable	Regression coefficient	value
Constant	0.914	<0.001
Performance of pars plana vitrectomy	0.502	0.002
Aphakia after initial trauma (L2)^1	0.960	<0.001
Loss of iris tissue	0.831	<0.001
Penetrating injury	−0.385	0.014
Cutting any prolapsed vitreous in the primary surgery	−0.506	0.021

⁢. ¹If L1 (the presence of traumatic cataract) = 0 and L2 = 1, the independent variable was aphakia during primary surgery.
