After adjusting for age, diabetes status, serum albumin level and residual renal function, the multivariable Cox regression model revealed that EOP was an independent risk factor for patient mortality (HR 2.03, RI 1.09–3.80, p = 0.026), technique failure (HR 1.69, RI 1.12–2.87, p = 0.015) and total survival (HR 1.73, RI 1.12–2.68, p = 0.013). Here, ALB is linked to diabetes mellitus.
