Association of self-efficacy, risk attitudes, and time preferences with health-related quality of life and functioning after total hip or knee replacement – Results of the MobilE-TRA 2 cohort

Table 3 Comparison of EQ-5D-5L at baseline and after three months between THR and TKR

		Baseline	Follow-up	Change	T2 vs. T1	Differences in change scores
	Group	Mean (SD)	Mean (SD)		p-value	p-value
Mobility	THR	3.28 (0.97)	2.00 (1.08)	− 1.28	< 0.001^a	0.053^b
Mobility	TKR	3.03 (1.04)	2.14 (1.06)	− 0.88	< 0.001^a	0.053^b
Self-care	THR	1.67 (0.96)	1.35 (0.60)	− 0.32	0.016^a	0.038^b
Self-care	TKR	1.35 (0.76)	1.32 (0.65)	− 0.03	0.811^a	0.038^b
Usual activity	THR	2.56 (1.19)	1.89 (1.02)	− 0.67	< 0.001^a	< 0.001^b
Usual activity	TKR	1.91 (1.07)	2.00 (1.03)	0.09	0.627^a	< 0.001^b
Pain	THR	3.67 (0.68)	2.13 (0.86)	− 1.53	< 0.001^a	0.001^b
Pain	TKR	3.30 (0.85)	2.36 (0.92)	− 0.94	< 0.001^a	0.001^b
Anxiety/depression	THR	1.60 (0.85)	1.39 (0.68)	− 0.21	0.092^a	0.363^b
Anxiety/depression	TKR	1.51 (0.83)	1.42 (0.69)	− 0.09	0.507^a	0.363^b

Higher values represent greater restrictions of HRQoL, negative change-scores imply improvement of symptoms
THR Total hip replacement, TKR Total knee replacement, EQ-5D-5L dimensions EuroQol Five-Dimensional Five-Level Questionnaire dimensions (1 - 5)
P-values for differences between baseline and follow-up within groups of THR and TKR were calculated using ^a t-test for paired samples. P-values for differences in change scores were calculated using ^b t-test for unpaired samples
