Longitudinal modeling of red blood cell distribution width dynamics and mortality risk in critically Ill patients with sepsis-associated acute kidney injury

Trajectories of RDW during follow-up visits.
We identified four distinct trajectories of Red Cell Distribution Width (RDW) changes during the 28-day follow-up period through group-based trajectory modeling (GBTM). The solid lines represent the average predicted levels of specific categories, serving as a function of follow-up estimated by the best-fitting model, and the shaded areas around the solid lines indicate the confidence intervals for the calculated trajectories.
