Notes:

BUN, blood urea nitrogen; CRP, C-reactive protein; TG, triglyceride; LDL, low-density lipoprotein; PTH, parathyroid hormone; RAASi, renin-angiotensin-aldosterone system inhibitors; Ccr, creatinine clearance rate; Kt/V, urea clearance index; PEW, protein energy wasting.

Categorical variables are showed as n (%). Continuous variables with normal distribution are reported as mean $\pm$ SD. Continuous variables with abnormal distribution are given as median (IQR).
