Table 1 Demographic and biochemistry characteristics of depressed and non-depressed subjects based on the Taiwanese Depression Questionnaire (TDQ) score (n = 151).

From: Affective and cognitive rather than somatic symptoms of depression predict 3-year mortality in patients on chronic hemodialysis

 

Total (n = 151)

No depression (TDQ 0–18) (n = 86, 57.0%)

  1. Data are presented as the mean ± standard deviation, or the count number (percentage). The p values are from the analyses between the participants with and without depression. ALKP: alkaline phosphatase, BUN: blood urea nitrogen, Ca x P: calcium and phosphate product, GOT: glutamic oxaloacetic transaminase, GPT: glutamic pyruvic transaminase, i-parathyroid hormone: intact parathyroid hormone, Kt/V: dialysis adequacy by dialyzer clearance of urea (K) times time (t) divided by volume (V) of the urea distribution, USD: US dollars.
