Hypertonic saline nasal provocation responses in CFS (thick line), normal (thin dark line), AR, and AS. A, Perceptions such as "Drip" (sensation of nasal discharge) were equivalent in CFS, AR, and AS and significantly higher than normal. B, Whereas the normal group had a significant dose response for axon response-mediated secretion of mucin, there was no dose dependence for the CFS group. AS indicates acute sinusitis.
