EuroQoL classification
Outcomes for the five dimensions of the EQ-5D and the VAS are listed in Table 3.
‘Mobility’ improved significantly during total follow-up for both treatment groups
(p< 0.001). However without a between group difference (p= .346) and controlled
for baseline measurements and age ‘group’ there was no statistically significant 2 difference in ‘Mobility’ (beta=-0.08, p=. 288).The 1-year linear trend in ‘Self-care’
and ‘Daily activities’ improves significantly for both treatment groups during follow-up (p< .001), again without a difference between groups (respectively p= .460 and p= .056). The 1-year linear trend in the EuroQoL ‘Pain & Discomfort’ scale displayed a statistically non-normal distribution. In ANCOVA it showed a significant and considerable deterioration, not only for both treatment groups (p< .001), but even more so for the control surgery group (p= 0.006; beta=-.21).The Mann-Whitney-U test on the Studentized residuals of the 1-year pain reduction, corrected for baseline measurements, also showed a statistical significance and confirmed the above results (p= 0.002).The 1-year linear trend in the EuroQoL ‘Anxiety-Depression’ scale also displayed a statistically non-normal distribution. In ANCOVA, the EuroQoL ‘Anxiety-Depression’ did not show any difference between groups (p= .267), even after applying the Mann-Whitney-U test on the Studentized residuals of these changes corrected for baseline measurements.
EuroQoL VAS thermometer
Overall the Visual Analogue Scale of the EuroQoL improved for both groups, from an average 61.5% pre-operative, up to 69.8% at final follow-up. The VAS showed an improvement in ANCOVA during the 12-month follow-up for both treatment groups (p< .001), but no group difference was observed (see Table 3, p= .488).
MFI-20 questionnaire
The results of the MFI-20 are presented in Table 4. In ANCOVA, the ‘General Fatigue’ and ‘Reduced Activity’ scale did improve for both treatment groups (p< .001) during 1-year follow-up, but there was no difference between groups (respectively p= .410 and p= .430).The ‘Physical Fatigue’ and ‘ Reduced Motivation’ scale also showed no difference between groups (respectively p= .299 and p= .264). Finally, the ‘Mental Fatigue’ scale in the 1-year follow-up improved highly for both treatment groups (p< .001), but again with no difference between groups (p= .804).
