Statistical analyses were performed using IBM SPSS, version 23. Independent t-tests and ANOVA with Bonferroni post-hoc tests were used to establish differences in mean scores for total PMH and its specific domains by socio-demographic and patient subgroups. To adjust for confounding effects, multiple linear regression analysis was used to determine the associations between each PMH domains and socio-demographic variables. All statistically significant differences were evaluated at p value < 0.05 using 2-sided tests.
