ARC-HBR (Urban 2019 Table 3)
ARC-HBR (Urban 2019 Table 3). High bleeding risk at PCI iff ≥1 major or ≥2 minor. Binary; no weighted point score. Caller-assigned booleans; magent does not assay labs or read NIHSS. Mutex (400): severe vs moderate CKD, Hb <11 vs mild anemia, major vs minor bleed, moderate-severe stroke <6 mo vs any other ischemic stroke. Not a DAPT duration. Not a medical device.
