Fig 2. Symptom scores across clinically adjudicated phenotypes.

Illness duration and symptom scores from each subject were compared between the different clinically adjudicated phenotypes. Symptom scores were graded on a 0 to 4 scale, with 0 indicating not present and 4 indicating “very severe”. Nasal symptoms represented an average of nasal discharge, nasal stuffiness, and sneezing. Overall symptom severity was simply the sum of all symptom scores. Most symptoms were similar between groups. Only two reached statistical significance: fever/chills (p = 0.005) and a composite of overall symptom severity (p = 0.02). Kruskal-Wallis statistical test was used to assess significance.
