  1. Performance: hypothetical average performance values, Weights: hypothetical weights obtained in DCE for stakeholder group 1 (P1) and 2 (P2), weighted aggregation: aggregation of standardised performance measures using weights for each stakeholder group
  2. aPerformance scores are standardised with the following formula: \( {S}_{aj}=\frac{x_{aj}}{{\left({x}_{aj}^2+\kern0.5em {x}_{bj}^2\right)}^{1/2}} \), where x = performance score on the natural scale, a = integrated care, b = comparator, j = criteria j
