The asterisks represent p-values of *p<.05, **p<.01, ***p<.001, for paired-sample t-tests between test and retest for each group. Paired sample t-tests were used as post-hoc tests following up a three-way interaction between Groups X Session X Frequency (Mixed ANOVA). The interaction was driven mainly by the simulated malingerers group, who were not consistent between test and retest at high frequencies (>6 kHz). The dotted line represents the border between standard audiometric measurements (<8 kHz) and very-high frequencies (>8 kHz).
