| Characteristic | MG Ocular (n=34) | MG General (n =36) | p |
|---|---|---|---|
| SBCT (median (range)) | 30.0 (15.0–51.0) | 25.0 (14.0–59.0) | 0.175 |
| PFM EU (L/min; median (range)) | 422 (345–612) | 427 (355–626) | 0.401 |
| PFM predicted (L; mean ± SD) | 82.9 ± 13.1 | 79.8 ± 15.2 | 0.701 |
| FVC1 (L; mean ± SD) | 2.1 ± 0.7 | 2.2 ± 0.6 | 0.279 |
