  • Data are presented as relative risks (95% confidence intervals). Relative risks were estimated using multivariable modified Poisson regression. Concerns were categorized empirically into health-related or psychosocial categories. “I’m doing fine on dialysis” and “No one has discussed KT with me” did not fall into either health-related or psychosocial concerns categories. See the Materials and Methods and the Supplemental Appendix for a description of the exploratory factor analysis used to categorize concerns. See Table 2 for individual concerns.
