  • 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.
