^aEstimated using a mixed-effects piecewise linear regression model with random intercepts, accounting for correlation within eye, participant and stimulus location, and adjusted for age and smoking status.

^bNo data at this visit for 3 fellow eyes and 3 study eyes of progressors.

Bolded numbers indicate P < 0.05.
