  1. 1Input variables were independently varied to determine the change in mortality rate or the change in costs which would have resulted in the value of sow space unit being equal to the value obtained in the baseline scenario
  2. 2Six countries were randomly coded as A, B, C, D, E and F due to anonymity requirements
  3. NA- not applicable, profitability requirements were not estimated for interventions with negative economic result
