Correlations between the change in systolic salt sensitivity and change in copeptin, in weight, and in 24 h urinary volumes, during low and high salt consumption.

ΔSBP
	All		Female		Male
	r	P	r	P	r	P
ΔCopeptin	−0,21	0,22	−0,58	0,02	−0,05	0,83
ΔWeight	0,27	0,08	0,33	0,18	0,25	0,29
ΔUrine volume	0,05	0,78	−0,13	0,61	0,27	0,25

ΔSBP, systolic salt sensitivity; ΔCopeptin, the change of copeptin during high salt intake and low salt intake; ΔWeight, change in weight; ΔUrine volume, change in urinary volume from high to low urinary volume; P, significance.
