Estimated Linear Regression Coefficients and Standard Errors for Refractive Error

Estimate SE P
Age (y) 0.038 0.008 <0.001
Gender (female) 0.49 0.085 <0.001
Age–gender interaction 0.021 0.011 0.049
Residual sib–sib correlation 0.35 0.057 <0.001

Data were obtained from the linear regression model of MSE refractive error on age, gender, and age-gender interaction. The sample comprised 967 subjects (mean age, 64.2 years) representing 1671 sib pairs.
