  1. Data presented as %
  2. A cut off of 2 divided the current, derivation cohort into < 20% or ≥ 20% mortality
  3. Using a score > 2 on the historical, validation dataset, 161 died out of 393 at risk, compared with an expected number of 223, whilst in those with scores ≤2, 41 died out of 349 at risk, compared with an expected number of 39
  4. In those with a score of 0 in the historical, validation dataset, one death was predicted and observed. A score of 0 had a NPV of 100% with a predicted and observed mortality < 5% though this only incorporated 7.5% (10/133) of the current, derivation cohort and 4.3% of the historical (32/741) cohort
