Distribution of META-PM grade in the UK Biobank sample and the BHAS replication sample.
| Grade | META-PM classification | Number of participants |
|
|---|---|---|---|
| UK Biobank | BHAS | ||
| C0 | No myopic maculopathy | 75,651 | 4533 |
| C2 | Diffuse atrophy | a | a |
| C3 | Patchy atrophy | 169 (0.22%) | 10 (0.22%) |

Images were graded using a deep learning algorithm. The grade assigned to each participant was that in the worse-affected eye.
