Respondents’ HRQoL scores
MH
The median scores of the eight domains ranges from 27.26 to 62.00. The three lowest median (IQR) scores were from the SF, RP and VT domains with 27.26 (10.03), 30.21 (11.23) and 34.77 (8.92) respectively. The three highest median (IQR) scores were from the BP, GH and RE domains with 62.00 (6.45), 47.48 (12.60) and 45.72 (16.54) respectively. As for the component summaries, the median (IQR) for the Physical Component Score (PCS) was 43.58 (7.44) and for the Mental Component Score (MCS) was 40.71 (8.77), as described in Table 
Median scores of each HRQoL domain among the respondents (Note: PCS is summarization of PF, RP, BP and GH, MCS is summarization of VT, SF, RE and MH.In terms of the baseline characteristic, the study indicated that there were no significant differences between the intervention group and the control group as for seven of the HRQoL domains, namely the BP (Z = -0.454, p = 0.650), the GH (F = 1.762, p = 0.745), the SF (Z = -1.225, p = 0.221), the RE (Z = -1.764, p = 0.078), the MH (Z = 0.996, p = 0.319), the MCS (F = 0.026, p = 0.114) and the PCS (F = 0.197, p = 0.251). However, there were significant differences between the intervention group and the control group as for three of the HRQoL domains, which were the PF (Z = -2.087, p = 0.037), the RP (Z -2.102, p = 0.036), and the VT (Z = -2.352, p = 0.019).Table
