Symbols are defined in the legends to Table 3.

Anxiety and depression in this table is determined by the Beck Anxiety Inventory and Beck Depression Inventory, respectively. The thresholds for diagnosing mild or more severe anxiety or depression are adapted from Beck et al (6,7).

Data are presented as mean ± standard deviation. All statistical comparisons are adjusted for age, gender, presence of diabetes, blood hemoglobin, and dialysis vintage.

Determined by ANOVA

^a,b

Significantly different from values in other columns with the same superscript (p<0.05), as determined by a Tukey’s honestly significant difference (HSD) test for pairwise comparisons

^†

Normal A−D− controls are significantly different from MHD A−D− patients as determined by Tukey’s HSD test: p<0.01.
