Results 
1. Plasma Na+ decreased during hemodialysis in LOWDialSOD study period (136.8 to 135.0 mmol/L, p=0.002). 

2. Pre-Na+ setpoint (137.4 to 136.8 mmol/L, p=0.03) and Pre-Na+ setpoint slope (0.014 to -0.015 mmol/L/day, p=0.009) decreased from HIGHDialSOD to LOWDialSOD study periods.

3. Interdialytic weight gain (2.15 vs 1.90 L, p=0.002), IDWG as % of target weight (IDWG%)(2.78 vs 2.39%, p=0.002), pre-dialysis systolic (143.3 vs 138.3 mm Hg, p=0.001), diastolic (78.6 vs 75.6 mm Hg, p=0.008) and mean arterial pressure (100.2 vs. 96.5 mm Hg, p=0.003), post-dialysis systolic (135.4 vs. 130.0 mm Hg, p=0.04), diastolic (75.8 vs 72.4 mm Hg, p=0.006) and mean arterial pressure (95.7 vs. 91.6 mm Hg, p=0.009) were higher in DIALHighSOD than DIALLowSOD. Hemodialysis frequency was associated with decreased (R = -0.295, slope = -0.002, p=0.034) IDWG%, while the opposite was seen with hemodialysis duration (R = 0.507, slope = 0.002, p<0.001). Hemodialysis duration increased intradialytic change in diastolic blood pressure (R=0.280, slope = 1.127, p=0.044), while hemodialysis frequency increased post-dialysis diastolic blood pressure (R=0.366, slope = 3.464, p=0.008)
