Results
Baseline
_Urinary Na/K ratio was 3.78 in intervention group and 3.64 in control group.
_Urinary Na was 199.2mmol (11.6g) in intervention group and 191.8mmol (11.2g) in control group.
_Urinary K was 56.4mmol (2.2g) in intervention group and 53.4mmol (2.1g) in control group.

Difference in urinary Na/K ratio before & after intervention
_Reduced 0.55 in intervention group and also reduced 0.05 in control group.
_No statistical significance observed in change of urinary Na/K ratio between intervention group and control group (p=0.09).

Difference in urinary Na before & after intervention
_Reduced 18.6mmol (1.1g) in intervention group and also reduced 8.8mmol (0.5g) in control group.
_No statistical significance observed in change of urinary Na between intervention group and control group (p=0.53).

Difference in urinary K before & after intervention
_Increased 2.5mmol (0.1g) in intervention group and reduced 1.5mmol (0.06g) in control group.
_No statistical significance observed in change of urinary Na between intervention group and control group (p=0.30).

Frequency of use of device in intervention group: average 2.77 [times/day] (Maximum: 7 [times/day])
