Scar width and scar quality
Table III shows that the intervention group had a lower median of scar width at 12 months than the control group which was a significant difference (p = 0.02).
The POSAS was used to measure scar quality. Unlike VSS, the POSAS has an extra dimension because the patient’s opinion is mandatory for a complete scar assessment. Table IV shows POSAS assessed by the patient. The POSAS assessed by the patients showed no significant difference between the intervention and control groups (p = 0.84). As table 4 depicts the POSAS assessed by the study nurse showed no significant difference between intervention and control group (p = 0.36).
