  2. Definition

    This codelist was taken from OpenCodelists, created by OpenSAFELY. We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.

    An updated version of https://codelists.opensafely.org/codelist/opensafely/stroke/, which contained some stray unmapped Read 2 codes.

    The original codelist had 49 Read 2 codes. These are replaced by 127 CTV3 codes.

  3. Methodology

    Unmapped Read 2 codes have been mapped to CTV3 by TPP. This was then reviewed by HD, AW, BMK and LT and a final codelist produced.
