  1. Abbreviation: HR hazard ratio
  2. Notes: 1. The incidence, timing, risk factors and outcomes of neurological events (stroke and TIA) after TAVI were analysed in the high-risk and inoperable cohorts of the PARTNER trial. Time-related events, including mortality following a neurological event, were then estimated by the Kaplan–Meier method (from Kapadia et al., 2016) [32]. HRs of mortality in patients with and without stroke were then derived using data on survival after stroke and expected survival had a stroke not occurred
