Overall Spearman coefficients for baseline/2-year HOOS and KOOS pain and function subscale scores versus total QOL score^*

	Knees	Hips
	QOL Spearman ρ (95% CI)	QOL Spearman ρ (95% CI)
Baseline H/KOOS pain	−0.03 (−0.06, 0.00)	0.06 (0.03, 0.09)
2-year H/KOOS pain	−0.63 (−0.64, −0.61)	−0.52 (−0.54, −0.50)
Baseline H/KOOS function	−0.06 (−0.09, −0.03)	0.02 (−0.01, 0.05)
2–year H/KOOS function	−0.63 (−0.65, −0.61)	−0.53 (−0.55, −0.52)
Baseline EQ-5D score	−0.09 (−0.13, −0.07)	0.00 (−0.03, −0.03)
2-year EQ-5D score	−0.50 (−0.52, −0.47)	−0.41 (−0.44, −0.38)
Baseline MCS	−0.10 (−0.13, −0.07)	−0.09 (−0.12, −0.06)
2-year MCS	−0.23 (−0.26, −0.20)	−0.19 (−0.22, −0.16)
Baseline PCS	−0.08 (−0.11, −0.05)	−0.01 (−0.04, −0.02)
2-year PCS	−0.49 (−0.51, −0.47)	−0.42 (−0.44, −0.40)

Note QOL scoring is 1 – best QOL, and 6 – worst QOL.

Spearman correlation coefficients were calculated to evaluate the correlation between each HOOS/KOOS pain/function subscale and total QOL score within hips and knees. Correlation estimates were converted to Fisher’s Z to ascertain 95% confidence intervals for the corresponding estimate.
