N/A: not applicable because the variable was not included in the multivariable regression model since its univariate association had p>0.10.

*:

the p-value is for testing whether there was a significant difference in the outcome event probability comparing the different groups. Wald test results were used.

**:

Fovea: loci located on the ring of 2° eccentricity. Parafovea: loci located on the ring of 4° eccentricity. Perifovea: loci located on the rings of 6° to 10° eccentricity.

(OR: odds ratio. CI: confidence interval).
