Evaluation of continuous constant current and continuous pulsed current in sweat induction for cystic fibrosis diagnosis

Table 6 Comparison of sweat weight values (mg) between pulsed current and continuous current, considering if an increase or reduction was observed in chloride concentration between pulsed current and continuous current

	Continuous pulsed current	Continuous constant current	N	p-value
Reduction of chloride concentration was observed from continuous pulsed current to continuous constant current^a	154 ± 52	197 ± 80	18	0.004
	140 (84 to 284)	0.188 (89 to 426)	18	0.004
Increase of chloride concentration was observed from continuous pulsed current to continuous constant current^b	207 ± 85	149 ± 45	34	< 0.001
	184 (102 to 535)	143 (80 to 292)	34	< 0.001

Statistical analysis conducted through Wilcoxon signed-rank test. Statistically significant data are in bold
^adata presented in Table 4 in orange and red
^bdata presented in Table 4 in blue, green, and yellow. The obtained sweat weight was associated with chloride concentration and may change the sweat test result because the amount of sweat collected could be cause in a dilution of the chloride in the own sweat. Statistically significant data are in bold. Data are presented in table as: number of individuals; mean ± standard deviation; median (minimum to maximum)
