Figure 4: Examples of “inconspicuous” spread of excitation measurement series in normalized representation. The constrictions mark the 95% confidence interval of the median and the quartiles. The whiskers show the simple interquartile range of the entire comparison group. Example A (male, 54 years, CI522) shows an insufficiently falling amplitude curve Example B (male, 32 years, CI422) shows a measurement series with a horizontal amplitude curve. Example C (female, 43 years old, CI24RE, re-implantation) shows an excessively steep amplitude curve.
