Fig. 2 — Effects of the progressive acute water restriction on urinary parameters: (a) urine specific gravity (USG) and (b) urine colour (U_col). Values are means for each experimental condition and for differences between the two conditions, with standard errors represented by vertical bars. *** Mean values were significantly different between the two experimental conditions at the corresponding time point (P< 0·001; ANCOVA). □, Control; , fluid deprivation; ▲, fluid deprivation minus control.
