Baseline VTE	0.51	5.53	11.3 / –10.3	0
ΔVTE Amil	–0.16	3.05	5.8 / –6.1	4.8
Δ VTE Low Cl-	0.06	3.57	7.1 / –6.9	4.8

Values were determined for baseline potential difference (V_TE), amiloride response (ΔV_TEAmil.) and low Cl^- solution response (ΔV_TELowCl ^-), from the Bland and Altman plot, for two measurements on the same 22 WT and 21 cftr ^-/- mice.
