Table 2.

Sensitivity, specificity, cutoff determination value (* indicates sensitivity > cutoff determination value, which indicates differentiating hypohydrated vs. euhydrated subjects), positive and negative predictive value, number of total diagnosed using respective WUT criteria, and distribution of subjects based on urine specific gravity (USG)>1.020 and urine osmolality >700 mOsmol. Gray shaded area indicates subjects defined as likely or very dehydrated (bold-faced text) or euhydrated for matching with number of WUT criteria (3, 2, 1, 0) met.
