Patients were divided into two categories; those with SLE (ICD9 code: 710.0) and those with other diagnoses. The most common diagnoses in the population with other causes of ESRD were structural urologic disease in pediatrics and diabetes mellitus in adults. Baseline characteristics of patients were calculated by race category and Hispanic ethnicity NAD using t-test for comparison of means and chi-squared tests for comparison of groups. We identified an inception cohort of patients who were started on hemodialysis (HD) in January 1990. Kaplan�CMeier survival analyses were performed in these patients using the time at risk from 1 January 1990 through 31 December 2010, the last date of the USRDS data collection period in this dataset. Patients were censored at renal transplantation or at the end of follow-up. Deaths were recorded from the death notification check details forms. Cox proportional hazard models were used to assess the risk of death in different races. In the USRDS dataset, information on race is divided into six categories: (i) Native American, (ii) Asian, (iii) African American, (iv) Caucasian, (v) unknown and (vi) other. Information on ethnicity is divided into two categories: (i) Hispanic and (ii) non-Hispanic. For this analysis, when examining differences in mortality by race, we focused on African American versus Caucasians not of Hispanic ethnicity. Other races were excluded because there were too few patients with SLE in the categories to perform statistical analysis. There were confounding of age by adjusting for age at dialysis initiation. The proportional hazard assumption was tested prior to calculating hazard ratios and was not violated. P-values of MK1775 dialysis in January 1990. There were 1720 total patients with ESRD secondary to SLE, 275 pediatric patients and 1445 adults. Of these patients, 94 were Caucasian pediatric SLE and 590 were Caucasian adults with SLE. There were 158 African American pediatric SLE patients and 738 African American adult patients with ESRD secondary to SLE. Demographic characteristics are presented in Table ?Table11. Table 1. Demographic characteristics There were 103 Hispanic children with ESRD secondary to other causes and 23 Hispanic children with ESRD secondary to SLE. These Hispanic children with ESRD secondary to SLE were older than children with other causes of ESRD with a mean age of 18.2 �� 1.8 versus 16.8 �� 2.
