This table presents the comparison of Patient Dignity Inventory scores before and after intervention between the two groups. Data are expressed as mean ± SD. Repeated measures ANOVA was used to analyze changes over time within each group and between-group differences. Significant improvements in all dimensions and total score were observed after treatment (P < 0.001), with the combined group showing greater reductions than the control group.
