Table 1.
Characteristic Table Showing the Number of Samples Used for Each Population Including: HL (Healthy Lighter-Skin), RL (Referable DR Lighter-Skin), HD (Healthy Darker-Skin), RD (Referable Darker-Skin), and H (Total Healthy), R (Total Referable DR), LS (Total Lighter-Skin) and DS (Total Darker-Skin), and Broken Down by Rows Corresponding to the Training (Including Training and Validation) for Both Baseline and Debiased DLS, as Well as Test Datasets. Healthy Implies no Diabetic Retinopathy (DR) Warranting Referable to a Health Care Provider.a

Denotes that these are oversampled by two to maintain the balance of healthy and diseased factors.
Denotes that these numbers are synthetic images.
