Linear regression was used to examine the association between explanatory variables and quality of life measured by DLQI. Explanatory variables with an association of p<0.2 in the bivariate analysis were included in the multivariate linear regression model. In the multivariate linear regression model, those explanatory variables with association at p<0.05 were considered statistically significant.
