Plasma protein-bound di-Tyr content in male and female ESRD patients. Mean (SE) of plasma protein-bound di-Tyr level in male and female ESRD patients before (pre-HD) and after (post-HD) a single HD session. Sex-specific mean values were compared by independent-sample t-tests.

Males	48	0.193 (0.005)	2.23	71	0.029
Females	25	0.170 (0.010)
di-Tyr post-HD
Males	47	0.174 (0.174)	2.11	70	0.039
