Solute plasma levels, clearance rates, and excretion rates for study participants.

<p>Means ± standard deviations</p><p>^† p < .05 Normal vs. ESRD</p><p>^° p< .05 Creatinine and TMAO clearances vs urea clearance within each group</p><p>^‡ p< .05 TMAO vs creatinine clearance</p><p>*Clearances are urinary clearances for normal and dialytic clearances for ESRD.</p><p>**Excretion is 24 hour urinary excretion for normal. For ESRD, removal is the amount removed in dialysate and ultrafiltrate divided by 2 to adjust for the 2 day interdialytic interval.</p><p>*** UN is urea nitrogen.</p><p>Solute plasma levels, clearance rates, and excretion rates for study participants.
