Association between GNRI groups and the mortality of severe stroke patients in propensity-score matched cohort.

Outcomes	Hazard Ratio (95% CI)	p Value
28-day mortality	1.38 (1.03–1.86)	0.03
90-day mortality	1.45 (1.11–1.89)	0.006
1-year mortality	1.51 (1.19–1.92)	0.001

Hazard ratio and 95% CI for the GNRI group in mortality at 28 days, 90 days, and 1 year mortality were calculated based on a Cox proportional hazard model. The high GNRI group (>98) was always considered the reference group. CI, confidence interval.
