Table 3 Correlations between hospital anxiety and depression scale-depression/hospital anxiety and depression scale-anxiety scores and Harris hip score at each time point

Time point	HADS-D vs HHS	HADS-A vs HHS
Baseline	r = -0.53, P < 0.001	r = -0.48, P < 0.001
6 months	r = -0.58, P < 0.001	r = -0.51, P < 0.001
1 year	r = -0.49, P < 0.001	r = -0.44, P < 0.001
2 years	r = -0.41, P < 0.001	r = -0.38, P < 0.001
3 years	r = -0.35, P = 0.001	r = -0.36, P < 0.001

HADS-D: Hospital anxiety and depression scale-depression; HADS-A: Hospital anxiety and depression scale-anxiety; HHS: Harris hip score.
