Random regression (multilevel) models of the effect of time, defined as age at testing beginning at 6 years old, in 46 children with unilateral hearing loss.

Outcome	Initial Status (SE)	Rate of Change (SE)	Pseudo R²
Full IQ	97.5 (2.7)^***	1.76 (0.59)^**	0.109
Verbal IQ	96.1 (2.9)^***	2.48 (0.76)^**	0.115
Performance IQ	100.0 (2.7)^***	0.34 (0.61)	0.017
Reading achievement	104.3 (2.4)^***	−0.24 (0.52)	0
Math achievement	93.8 (2.8)^***	0.50 (0.72)	0
Writing achievement	99.8 (3.4)^***	1.44 (0.93)	0.026
Listening comprehension	90.6 (2.4)^***	1.04 (0.69)	0.045
Oral expression	85.5 (2.8)^***	2.87 (0.70)^***	0.149
Oral composite	85.3 (2.7)^***	2.48 (0.72)^**	0.168

Note: The Initial Status provides the model’s calculated mean baseline score at the age of 6 years. The Rate of Change indicates the slope of the change in scores over time (i.e., calculated change in score per year). The Pseudo R² values provide the proportional within-person variance that is explained by the effect of time.
