Analysis: After demonstrating that the multi-level model was correct, with the measurement time points as first level and the patients as second, a multivariate model was fitted. Results: In bivariate analysis EVA rate (EQ-5D) was associated with the ""anxiety"" and ""depression"" and ""pain"" to ""depression"" but not ""anxiety"" or ""depression"" were significant in multilevel models. Conclusion: Neither anxiety or depression influence the evaluation of the physical quality of life after this surgery.
