— | — | ischemic stroke - ischemic stroke events in REGARDS were identified through biannual surveillance and adjudicated via medical record review. For participants aligned to Medicare claims, additional ischemic stroke events were identified from inpatient claims using ICD-9 codes 433.x1 or 434.x1 or ICD-10 codes I63.xx in the primary diagnosis position. Hospitalizations occurring within one day of each other were merged into a single episode of care. Participants with self-reported stroke at baseline were excluded. |

European | — | AllofUs | To harmonize phenotype definitions with REGARDS, analyses in All of Us were restricted to participants aged ≥45 years. IS cases were defined as individuals with an inpatient encounter associated with ICD-9 codes 433.x1 or 434.x1, or ICD-10 codes I63.xx. Stroke codes identified only in non-inpatient encounters, SNOMED stroke codes, and hemorrhagic stroke codes (ICD-9 430.x, 431.x; ICD-10 I60.x, I61.x) were excluded from both case and control sets. |
