  • The estimated effect size and 95% CI in the mean global language score associated with the stated change in the age at intervention (eg, “compared with fitting at 3 mo, fitting at 6 mo” is expressed as “3 → 6”), if the other predictor variables are constant. The degree of hearing loss is expressed in terms of BE4FA in dB HL.
