  1. * Outcome = proportion surviving; † Outcome = proportion not dead or dependent (defined as mRS<4). ‡ Outcome = QALYs gained; §Differences in 95%CI around incremental cost in analyses 1, 3 & 5 due to random error from non-parametric bootstrap.
  2. ** Threshold of £30,000 only appropriate to £/QALY.
