Recent clinical practice guidelines recommend the creation of an arteriovenous (AV) vascular access (ie, native fistula or synthetic graft) before the start of chronic hemodialysis therapy to prevent the need for complication-prone dialysis catheters. We report on the association of referral to a nephrologist with duration of dialysis-catheter use and type(More)
Native arteriovenous (AV) fistulae for hemodialysis vascular access are believed to be associated with fewer complications than synthetic polytetrafluoroethylene (PTFE) grafts. We conducted a study among patients in the Dialysis Morbidity and Mortality Study to compare risk factors for complications of AV fistulae and PTFE grafts in men and women and to(More)
The three latent components of the outcome (tGFR, systematic errors and random errors) were assumed to be independent with standard normal distribution, Normal (0, 1). In some situations, when the random errors are dependent on the underlying trait because the measurement error is proportional to the size of the measurement, the dependence can be removed(More)
