When a stroke strikes, the window for sound clinical judgment is narrow and the stakes are absolute. Across 77 hospitals in China, researchers asked whether artificial intelligence could help physicians make better decisions in that compressed moment — and over 21,603 patients and two and a half years, the answer proved measurable: a 27 percent reduction in secondary vascular events at one year. The trial, published in The BMJ in March 2026, does not herald the replacement of human judgment, but rather its augmentation — a quiet demonstration that well-designed tools can help medicine keep its
