Study on frailty trajectories and their association with mortality risk in elderly hemodialysis patients: an analysis based on a multi-state Markov model

Background Frailty is common in older adults receiving maintenance hemodialysis (MHD) and predicts death, yet it changes in both directions over time. Most studies treat frailty as a single baseline or time-updated covariate and do not jointly estimate worsening, recovery, and mortality. Objectives To describe frailty...
