Outcomes at 3 years (global outcome factor score) in relation to earlier PEACH score. The solid line is the predicted value of the factor score as the earlier PEACH score varies, with early intervention mode fixed at oral only, no change in intervention mode over the first 3 years, maternal education fixed at diploma or certificate level, and other predictors fixed at their mean values. The shaded area shows the pointwise 95% confidence intervals for the mean values. Filled symbols depict scores of children with hearing aids (HA only), and open symbols depict scores of children with cochlear implants (CI).
