Note that the table includes all the patients under each of the three subgroups diabetic retinopathy (DRP), age-related macular degeneration (AMD), and glaucoma. Thus, for example, a patient listed under ‘Yes’ for DRP might also be listed under ‘Yes’ for AMD, and a patient under ‘Yes’ for DRP might also be listed under ‘No’ for glaucoma.
*In pairwise comparisons using χ2 tests, all combinations were statistically significant.
†In pairwise comparisons using χ2 tests, all combinations were statistically significant except for steroids versus steroids and non-steroidal anti-inflammatory drugs (NSAIDs) (p-value 0.98).
