Self-management advice, exercise and foot orthoses for plantar heel pain: the TREADON pilot and feasibility randomised trial

Table 6 Responsiveness and association of change in possible primary outcomes with global change and EQ5D

	Baseline mean (SD)	12 weeks mean (SD)	Change^a, mean (SD)	Responsiveness^b	With global change		With EQ5D change
	Baseline mean (SD)	12 weeks mean (SD)	Change^a, mean (SD)	Responsiveness^b	Spearman’s correlation	AUC (95% CI)^c	Spearman’s correlation
NRS change	5.9 (1.9)	3.3 (2.4)	2.6 (2.5)	1.04	0.60	0.88 (0.79, 0.96)	0.87
FFI-pain change	50.6 (17.7)	32.8 (23.9)	21.6 (22.4)	0.96	0.74	0.84 (0.69, 0.99)	0.71
MFPDI-pain change	14.0 (2.8)	12.3 (3.5)	1.7 (3.0)	0.57	0.57	0.72 (0.58, 0.67)	0.75

^aChange from baseline to 12 week
^bResponsiveness statistic (standardised response mean = mean change in score / SD of change scores; usually interpreted against the benchmarks ≤ 0.2: small, 0.5: moderate, ≥ 0.8: large [35])
^cGlobal change dichotomised as (completely recovered or much better / somewhat better or no change or somewhat worse or much worse)
