Table 2

Stepwise, multiple regression analysis of the visual acuity of the better eye. The constant illustrates a predictive value of a visual acuity of 0.77 in a child without ROP or neurological complications. The acuity will be reduced to 0.68 if neurological complications are present and to 0.52 if the child also has ROP and is given cryotherapy
