The association of standard Kt/V and surface area‐normalized standard Kt/V with clinical outcomes in hemodialysis patients

Introduction A previous study demonstrated that the surface area‐normalized standard Kt/V (SAstdKt/V) was better associated with mortality than standard Kt/V (stdKt/V). This study investigates the association of SAstdKt/V and stdKt/V with mortality, anemia, and hypoalbuminemia in a larger patient cohort with a longer follow‐up period. Methods We included adult patients on thrice‐weekly hemodialysis in the USRDS database and excluded amputated patients. StdKt/V and SAstdKt/V were calculated from the available single‐pool Kt/V. Patients were categorized into five groups according to their stdKt/V and SAstdKt/V:
