*Base case analysis uses the original method of imputation, values a rehabilitation day as a hospital treatment day, calculates production losses by means of the friction cost method, uses the societal perspective to calculate total costs and calculates utilities with a Dutch tariff. Sensitivity analyses uses mean imputation to calculate total costs, values a rehabilitation treatment day as a rehabilitation contact, calculates production losses with the human capital approach, estimates of total healthcare costs and utilities are calculated with a UK tariff.

†If CI includes 0, no significant difference is found.

‡Significant differences estimated by means of the Wilcoxon signed-rank test; Critical p=0.005.
