  1. a The diagnosis episode was the episode where the lung cancer diagnosis was made or the first episode occurring in the interval from 7 days before to 14 days after the lung cancer diagnosis. Episodes outside this interval were excluded from the analysis, n = 1591. There was no matching HIPE data for n = 1412 decedents. The denominator data is n = 2183 for short term survivors and n = 8659 for longer term survivors
  2. b Due to small cell numbers (n = 11), ‘Stage 0’ classification was merged with ‘Stage I/II’ classification
  3. c Due to small cell numbers (n = 21), ‘Sarcoma’ classification was merged with ‘unspecified malignant’ classification. Morphologies based on International Agency for Research on Cancer classification [21]
