Figure 7

Correlations between auditory thresholds shifts and bladder gas volume at the indicated frequencies. Threshold shifts in each individual after gas removal were plotted against bladder volume. N = 9 for all frequencies. Regression equation with R squared (R 2) and Pearson’s correlation coefficients (r) with p values are shown. Significant correlations (p < 0.05) were observed at 3.0 and 5.0 kHz.
