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