Receiver Operating Characteristic Curves.

<p>Abbreviations: CDS, Clinical Dehydration Scale; WHO, World Health Organization; G, Gorelick; MD, Physician.</p

Subgroup analysis by age of child from which each scale was derived.

<p>Abbreviations: CDS, Clinical Dehydration Scale; AUC, area under the receiver operating characteristic curve; CI, confidence interval.</p

Test characteristics.

<p>*The cut point refers to the position on the receiver operating characteristic curve that corresponds to the best test characteristics for the Clinical Dehydration Scale (CDS), Gorelick scale, and physician gestalt respectively. The World Health Organization (WHO) scale test characteristics are based on a predefined cut point. Abbreviations: AUC, area under the receiver operating characteristic curve; SN, sensitivity; SP, specificity; LR+, likelihood ratio positive; LR-, likelihood ratio negative.</p
