Bland and Altman plot considering the agreement between the sweat chloride values achieved from continuous pulsed current and continuous constant current. a Sweat chloride values achieved from continuous pulsed current and continuous constant current – R = 0.062; R2 = 0.004; p-value = 0.368; Bias = 1.806; ULA = 23.386; LLA = − 19.774. b Sweat chloride values achieved from sinusoidal pulsed current and continuous constant current – R = 0.027; R2 = 0.001; p-value = 0.855; Bias = 4.891; ULA = 22.502; LLA = − 12.72. c Sweat chloride values achieved from triangular pulsed current and continuous constant current – R = 0.074; R2 = 0.005; p-value = 0.349; Bias = 0.879; ULA = 23.254; LLA = − 21.496. ULA, upper limit of agreement; LLA, lower limit of agreement. The chloride concentration is shown as milliequivalent by liter (mmol/L). The statistical analysis was done with simple linear regression. Alpha = 0.05
