↵a In control group, n = 41 for baseline step count, n = 44 for HADS, and n = 43 for EQ-VAS.
↵b In intervention group, n = 37 for baseline step count, and n = 42 for EQ-VAS. P > 0.05 for all comparisons except:
↵c sex (P = 0.008) and
↵e EQ-5D (P = 0.03).
↵d Socioeconomic status was measured at the individual level by whether participants were ‘medical card eligible’, a means-tested health benefits scheme. BMI = body mass index. EQ-VAS = EuroQol visual analogue scale quality-of-life scoring tool. HADS = Hospital Anxiety and Depression Scale. SD = standard deviation.
