The CT-confirmed ARS model consisted of seven variables (previous diagnosis of ARS, preceding URTI, anosmia, double sickening, purulent nasal discharge on examination, need for antibiotics as judged by physician, and CRP), whereas the model for culture-confirmed ABRS consisted of only three variables (pain in teeth, purulent nasal discharge on examination, and CRP). This evidence concerns the gene CRP and Kallmann syndrome.
