Fig. 1.
Ipsilateral secretory effects of unilateral nasal challenge with normal
saline vs. hyperosmolar saline in 23 subjects with active allergic
rhinitis. Individual secretion weights obtained before (Pre) as well as
1 and 5 min after challenge are shown. Thick marks represent mean data
from each time point. The 3 values within each data set were first
compared by using Friedman's ANOVA. This was followed by comparison of
pre- and postchallenge values by using Wilcoxon signed-rank paired test
(P values shown). Evaluation of
changes between pre- and postchallenge values showed significantly
increased ipsilateral secretions induced by hyperosmolar saline,
compared with normal saline
(** P < 0.0001 and * P = 0.0002).
