  1. 1total number of men (N), 2number and % with prolonged LOS (n, %), 3adjusted odds ratios (OR) with 95% confidence intervals (CI) and 4p-values, 5count of morbidities included in the Elixhauser index on HIPE record relating to the RP episode, 6median number of RPs performed at hospital per year, 7median number of RPs performed by surgeon per year in public and private hospitals.
  2. * Variables tested, but not significantly associated with prolonged LOS, and excluded from the final model: age at diagnosis, smoking status at diagnosis, and deprivation index of area of residence, grade/Gleason score and patient status at discharge (public/private to the consultant). See Additional file 1 for the ORs for these variables.
