Values for continuous variables are shown as mean ± standard deviation after analysis by Student's t test; variables not normally distributed are shown as median and interquartile range after analysis by the Mann–Whitney U test; values are presented as number (%) and analysis after analysis by the chi-squared test. A-FABP, adipocyte fatty acid binding protein; CAPD, continuous ambulatory peritoneal dialysis; weekly Kt/V, weekly fractional clearance index for urea; ACE, angiotensin-converting enzyme; ARB, angiotensin-receptor blocker; CCB, calcium-channel blocker. < 0.05 was considered statistically significant.
