Group With HAs
| Age at Amplification | Estimate and 95% CI | ||
|---|---|---|---|
| BE4FA = 30 dB HL | BE4FA = 50 dB HL | BE4FA = 70 dB HL | |
| 3 → 6 | −0.7 (−4.3 to 2.9) | −2.3 (−5.4 to 0.8) | −4.0 (−7.6 to −0.4) |
| 6 → 12 | −0.6 (−2.8 to 1.6) | −2.3 (−3.6 to −0.9) | −3.9 (−6.3 to −1.6) |
| 12 → 18 | −0.3 (−2.3 to 1.6) | −1.3 (−3.0 to 0.4) | −2.3 (−4.3 to −0.2) |
| 18 → 24 | −0.2 (−1.8 to 1.4) | −0.9 (−2.4 to 0.6) | −1.6 (−3.3 to 0.1) |
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.
