Figure 2.

Urine antigen concentrations in case and control episodes with different characteristics. The dashed line at 0.07 ng/mL represents the cutoff for positivity. Each point above the dashed cutoff line represents a positive result. The number in the box below the dashed line represents the number of patients with negative results, and the number below each column represents the total number of patients tested. Results shown at the hashed line at the top of the figure are above the limit of quantification of the assay and are expressed as 8.2 ng/mL. Abbreviations: ICM, immunocompromised; ICP, immunocompetent.
