- aCorrelation coefficients are shown for the total sample. Analysis was done for male and female subsamples as well. If not indicated (g), correlation coefficients for male and female subsamples are above the required threshold (confidence intervals do not include 0.5)
- bPearson’s correlation coefficient (r)
- cSpearman’s rank correlation coefficient (rs)
- dCorrelation OHS change score
- eCoefficients for OHS pain subscale
- fCoefficients for OHS function subscale
- gLarge correlation was not confirmed for the male subsample (absolute values of the confidence interval limits were required to be ≥0.5)
- hLarge correlation was not confirmed for the total sample and male subsample (absolute values of the confidence interval limits were required to be ≥0.5)
