Longitudinal trajectories were identified using a two-stage approach combining linear mixed-effects modeling and K-means clustering. Associations were assessed using sequential multivariable Cox proportional hazards models adjusted for demographics, diabetes mellitus, cardiovascular disease, baseline serum albumin, high-sensitivity C-reactive protein, hemoglobin, phosphate, urea reduction ratio, and time-average prealbumin. Multiple imputation by chained equations was employed to handle missing covariates, ensuring the inclusion of the full cohort (N = 326) in all multivariable models.</div></div><div>We conducted a retrospective cohort study of 326 prevalent MHD patients with 3,137 serial prealbumin measurements (median follow-up 2.25 years; average 9.62 measurements per patient).
