Comparison	Estimate With 95% CI
First Year Progression for 7-year onset (D)	−0.58 (−0.69, −0.48)
First Year Progression for 8-year onset (D)	−0.51 (−0.60, −0.42)
First Year Progression for 9-year onset (D)	−0.44 (−0.51, −0.37)
First Year Progression for 10-year onset (D)	−0.37 (−0.43, −0.31)
First Year Progression for 11-year onset (D)	−0.30 (−0.36, −0.24)
First Year Progression for 12-year onset (D)	−0.23 (−0.30, −0.17)
First Year Progression for 13-year onset (D)	−0.16 (−0.24, −0.08)
Difference in first year progression for children who are a year apart in onset age (D)	0.07 (0.05, 0.09)

The estimates assume a baseline SPHEQ of −0.75 D and an equal proportion of males and females. The estimates also assume the following mix of race/ethnicity: Asian American 5.5%, Black 14.2%, Hispanic 26.8%, Native American 0.8%, White 52.7%. CI, confidence interval.
