Abstract | BACKGROUND AND AIMS: METHODS AND RESULTS: We measured baseline serum netrin-1 levels in 3065 ischemic stroke patients from China Antihypertensive Trial in Acute Ischemic Stroke (CATIS). The primary outcome was a combination of death and major disability (modified Rankin Scale score≥3) at 3 months after ischemic stroke. Total cholesterol (TC) levels could modify the association between netrin-1 and prognosis of ischemic stroke (Pinteraction = 0.040). After multivariate adjustment, the odds ratios of the primary outcome associated with the highest quartile of netrin-1 were 0.39 (95%CI, 0.17-0.90; Ptrend = 0.004) for the patients with high TC levels and 0.82 (95%CI, 0.61-1.11; Ptrend = 0.149) for those with normal TC levels. Adding netrin-1 to conventional risk factors improved risk prediction for the primary outcome in the patients with high TC levels (net reclassification improvement: 26.8%, P = 0.015; integrated discrimination index: 1.6%, P = 0.028) but not in those with normal TC levels. CONCLUSIONS: Elevated netrin-1 is associated with improved prognosis at 3 months after ischemic stroke in the patients with high TC levels but not in those with normal TC levels. Further prospective studies from other populations and randomized clinical trials are needed to verify our findings and clarify the potential mechanisms.
