ABRS = acute rhinosinusitis; DOR = diagnostic odds ratio; LR+ = positive likelihood ratio; LR− = negative likelihood ratio.
Note: Each sign or symptom was reported in 3 or more studies to be included here.
↵a A likelihood ratio near 1.0 means that the test adds little diagnostic information, a likelihood ratio >1 increases the likelihood of disease, and a likelihood ratio <1 decreases the likelihood of disease.
↵b The diagnostic odds ratio is LR+ divided by LR− and is an overall measure of diagnostic discrimination.
↵c Value is significantly < or > 1.0.
↵d Cacosmia is fetid odor on patient’s breath.
