RESEARCH DESIGN AND METHODS Adults with type 1 diabetes from the T1D Exchange Registry/online communities completed the survey and contributed retrospective CGM data for up to 1 year. Self-reported glycemic outcomes

Of the nearly 600,000 people in the U.S. who receive dialysis for chronic kidney failure, >60% have diabetes. People receiving dialysis who have diabetes have worse overall and cardiovascular survival rates than those without diabetes. Diabetes care in the dialysis setting is complicated by kidney failure–related factors that render extrapolation of glycated hemoglobin (HbA1c) targets to the dialysis
