Figure 1: Patterns of hearing loss and asymmetry by gender. (a) Thresholds by gender - summary box plots extend from the 25th to 75th percentiles, with a midline at the median, "+" at the mean and vertical lines extending to the 5th and 95th percentiles. (b) Mean thresholds by ear and gender - shaded region extends to the mean for women at each frequency, while "♦" shows the corresponding mean for men. (c) Asymmetry by gender - individual subject differences between ears (left minus right) are summarized with box plots (described in a). (d) Mean asymmetry by gender - for individual subjects showing at least a 5 dB change from baseline at one or more high frequencies (3-8K Hz), the mean asymmetry (left minus right ear) over the high frequencies is plotted versus the maximum change from baseline. Filled (open) circles show results for women (men), while solid (dashed) lines illustrate trends using a cubic spline smoothing function for women (men)
