Multivariate adjusted analyses
After adjusting for transplant-associated variables, race was not found to be associated with patient reports of QoL post-HSCT (Table 2). Inclusion of socioeconomic variables in these analyses, such as income (Table 3) and insurance type (Table 4) did not result in significant associations between patient race and QoL scores.
Unlike patient race, patient diagnosis associated with physical functioning scores, indicating that patients with non-malignant conditions were likely to have greater physical functioning than patients with malignant conditions (p = 0.039). This effect persisted when analyses evaluated potential interactions of race and estimated household income (Table 3, p = 0.04), but was not significant in analyses highlighting the interaction of race and insurance type (Table 4).
In supplementary analysis, White patients were used as the control group (exponentiated coefficient = 1) to be able to probe more specific two-group analyses. Hispanic, Black, and Native American patients did not have QoL scores that differed from those of White patients across all five types of functioning when controlling for transplant characteristics (Supplemental Table S2) and socioeconomic factors (Supplemental Table S3).
