The significant independent variables after the backward stepwise elimination.

Independent variable Regression coefficient value

Constant0.914<0.001
Performance of pars plana vitrectomy0.5020.002
Aphakia after initial trauma (L2)10.960<0.001
Loss of iris tissue0.831<0.001
Penetrating injury−0.3850.014
Cutting any prolapsed vitreous in the primary surgery−0.5060.021

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