Impedance parameter	Bolus transit rate (%)		TBTT (s)
Impedance parameter	Liquid	Viscous	Liquid	Viscous
Normal	88 ± 18	72 ± 28^d	6.5 ± 1.3	7.6 ± 1.5^d
IEM	59 ± 16^b	61 ± 27^b ^d	7.4 ± 1.6^b	8.3 ± 1.4^b ^d
Nutcracker esophagus	98 ± 8^b	98 ± 5^b ^d	6.0 ± 1.2^b	6.9 ± 1.4^b ^d
Scleroderma	9 ± 14^b	3 ± 5^b	-	-

^b

P < 0.01, vs normal by manometric diagnosis upon liquid swallows and viscous swallows (ANOVA);

^d

P < 0.01, vs liquid swallows (unpaired t-test).
