| Age at onset (ref: <20) | 1 (reference) | – | 1 (reference) | – |
| 20–29 | 1.09 (0.22 to 5.40) | 0.135 | 0.05 (<0.001 to 4.50) | 0.201 |

*Binary logistic regression (reference: MS). Control variables included BMI, age at onset (categorised every 10 years). BMInaive, which is measured within 1 month of their disease onset and measured before the use of steroid treatment.
BMInaive, body mass index is measured within 1 month of their disease onset and measured before the use of steroid treatment; NMOSD-AQP4, neuromyelitis optica spectrum disorder with aquaporin-4 immunoglobulin G.
