Weighted cumulative consumption of analgesic medications (intention-to-treat cohort). Weighed cumulative intake of analgesic medication (in mg), according to the in-house classification (Table 2) for patients in the fast-track rehabilitation group and the standard rehabilitation group. Except for the first 2 days after the surgery, patients in the fast-track rehabilitation group needed a significantly lower amount of analgesic drugs than patients in the standard rehabilitation group (Wilcoxon test p = 0.0019; ITT cohort)
