	Women	P value	Total	P value
	HR (95% CI)	P value	HR (95% CI)	P value
Death
Low BMI_min-1yr (<18.5 kg/m²)	19.26 (1.73 to >99 999)	0.013	8.50 (1.33 to 98.59)	0.024
Age of onset	1.06 (0.97 to 175.06)	0.186	1.05 (0.98 to 1.13)	0.148
Short-term use of oral steroid	1.08 (0.00 to 17.09)	0.955	1.09 (0.07 to 10.94)	0.942
Continuous use of oral steroid	6.89 (0.40 to >99 999)	0.165	2.50 (0.23 to 19.94)	0.402
Use of immunosuppressant	0.83 (0.00 to 19.44)	0.889	0.86 (0.08 to 16.27)	0.908

BMI_min-1yr, the lowest body mass index measured within 1 year of the first symptoms;NMOSD-AQP4, neuromyelitis optica spectrum disorder with aquaporin-4 immunoglobulin G.
