Impaired fasting glucose is comparable to diabetes mellitus in predicting mortality and cardiovascular events in patients undergoing peritoneal dialysis: the role of β-cell function and insulin resistance

= 0.02), with risks comparable to those observed in DM. The TyG index independently predicted both outcomes, whereas greater β-cell function was associated with a reduced risk of both endpoints. These findings suggest that cardiovascular and mortality risks in IFG are comparable to those in DM among PD patients, potentially mediated by β-cell dysfunction and increased IR.
