Red blood cell distribution width is an indicator of physiological dysregulation and reveals the relationship between biomarkers and health status in hemodialysis patients

Key takeaways

Red blood cells come in a range of sizes, and how spread out that range is can be measured with a common blood test (red cell distribution width). In people on dialysis, a wider spread tracked with worse overall health and with other markers of body stress. This is an observational study, so it shows a link, not proof that the wider spread causes harm. It is a preprint and has not passed peer review yet.
