  1. Horses (n = 236) operated for colic between 2006 and 2012 in University of Helsinki, Equine Teaching Hospital, Finland
  2. aPercentages calculated out of the values in the Total-column
  3. bHorses whose owners could not be reached and therefore specific data on postsurgical convalescence could not be acquired. These horses were included in the survival analysis as the date and reason of death were available from the hospital records and national databases (Heppa® database of the Finnish Trotting Association Hippos, Helsinki, Finland)
  4. cHorses of which no records and information were available after discharge. These horses were excluded from all the statistical analyses
