Notes:
a
Estimated by using a binary regression model with image quality <4 or ≥4 as the outcome variable and age, comfort using a smartphone, and comfort in assessing problems with the eye as predictors;
b
median age was used, as the distribution was non-normal when tested by using the Shapiro–Wilk test statistic;
c
calculated by 10-year intervals in age;
d
EyeGo users were asked these two questions prior to screening.
