Na measurement method	At programmed DNa 135 mEq/L*				At programmed DNa 136 mEq/L**
	F4008H	F5008S (n = 10)		BB (n = 10)	F4008H (n = 10)	F5008S (n = 4)	BB (n = 11)
ISE measured minus programmed DNa	NA		6 (4.75−7.25)	7.5 (7−9)	5.5 (4.75−8.75)	NA	6 (6−7)
FP measured minus programmed DNa	NA		4 (1.75−5)	7 (6−7)	4.5 (0.75−6)	NA	8 (7−8)
IC measured minus programmed DNa	NA		4.5 (1.75−5.25)	6 (6−7)	5 (3.75−5)	2.5 (2−4.5)	5 (4.75−5.25)

Results expressed as median (IQR).

^*P < 0.05 between F5008S/BB when DNa measured by all methods.

^**P = 0.004 between F4008H/BB when DNa measured by FP.
