1. Effect of intervention differed across racial and socioeconomic groups.
Effect of intervention differed across racial and socioeconomic groups. The effect of intervention by racial group is illustrated in A (likelihood ratio [LR] test for interaction in adjusted analyses, P=0.02). The effect of the intervention by insurance status is illustrated in B (LR test for interaction in adjusted analyses, P=0.14). (C) Interaction by educational level was not significant in crude and adjusted analyses. (D) The effect of the intervention differed by neighborhood poverty (LR test for interaction in adjusted analyses, P=0.01). Analyses were adjusted for age, sex, race, time of entry into study, duration of dialysis, history of cardiovascular disease, health insurance, employment status, educational attainment, and neighborhood poverty.
