Fig. 1

Distribution of blood eosinophils across two serial measurements. Individual patients are shown along the horizontal axis. The top panel shows data for patients with blood eosinophils that were persistently below 300 cells/μL. The middle panel shows data for patients with blood eosinophils that varied around 300 cells/μL. The bottom panel shows patients with blood eosinophils that were persistently equal to or greater than 300 cells/μL. Nine and fourteen participants had counts above 1000 cells/μL in the variable and persistently high groups, respectively (not shown). *The horizontal line at 300 cells/μL is defined as peripheral eosinophilia
