To further probe this signal, future studies should integrate time-resolved sampling with survival analyses (e.g., Cox models) that adjust for stroke subtype, vascular territory, and comorbidity burden, testing whether NK/NKT signatures (NKG2D, IFN-γ) and oxidative markers (MDA, SOD-1) independently associate with time to death across ages. This evidence concerns the gene SOD1 and stroke disorder.
