Figure 1. Distribution of equilibrium pH of freshly excised sinonasal epithelia.

Figure 1

Individual equilibrium pH values are plotted and average values are shown as horizontal bars. Nasal epithelia from homozygous ΔF508 CF individual had significantly lower equilibrium pH (pH = 7.08 ± 0.09), compared to nasal epithelia from normal and CRS without asthma (p = 0.041). N refers to the number of tissue from different individuals. Error bars represent SEM (standard error of the mean); * denotes a significant difference (p < 0.05).
