Moderate-to-severe LA is associated with 1-year stroke recurrence in multivariate Cox regression analysis
| HR (95% CI) | P-value | |
|---|---|---|
| Age | 1.025 (0.999–1.053) | 0.063 |
| Male | 1.256 (0.664–2.379) | 0.483 |
| Admission TG | 1.198 (1.015–1.413) | 0.033 |
| Hematoma location (lobar/non-lobar) | 0.759 (0.360–1.600) | 0.468 |
| SBI | 2.965 (1.571–5.597) | 0.001 |
| LA severity | 1.300 (0.959–1.762) | 0.091 |
| Mild | 1.359 (0.332–5.567) | 0.670 |
| Moderate to severe | 2.712 (1.058–6.948) | 0.038 |
LA severity was entered as an ordinal categorical variable (no vs. mild vs. moderate vs. severe). Stroke recurrence was defined as readmission to hospital with a definite diagnosis of stroke. LA: Leukoaraiosis; SBI: silent brain infarction; TG: triglyceride.
