Change in Cardiff Wound Impact Schedule domain scores between start and end of the study having adjusted for influence of baseline measurement taken at week 1. Each domain is transformed to a score of between 0 and 100. Differences in mean score changes between patients treated with NLFU + SOC and those treated with SOC alone are shown

Cardiff Wound Impact Schedule domain	NLFU + SOC (n = 17)	SOC (n = 19)	Difference (95% CIs)	P‐value*
Well‐being	8·3 (SD, 16·2)	8·0 (SD, 16·2)	0·4 (−10·6 to 11·4)	0·943
Physical symptoms and daily living	10·4 (SD, 10·7)	5·8 (SD, 10·7)	4·6 (−2·6 to 11·9)	0·204
Social life	3·0 (SD, 19·8)	−0·5 (SD, 19·8)	3·5 (−10·0 to 17·0)	0·601

CI, confidence interval; NLFU, non‐contact low‐frequency ultrasound; SD, standard deviation; SOC, standard of care.

^*Influence of the covariate of baseline (week 1) measurement of each domain is significant at P < 0·05 across all three domains.
