  • *The worst possible score that could be reported for all the missing postoperative data in order for the short-term (6 months) or long-term statistics in tables 3 and 4 to still be significant. (The test statistics that were not significant (NS) to start with have not been included.)

  • †A high EQVAS or EQ5D index score is associated with an improvement in QoL, whereas with all other QoL and symptom scores, a low value is associated with improvement.

  • EQ5D, EuroQol 5D; EQVAS, EuroQol Visual Analogue Scale; QoL, quality of life.
