Fig 1 Comparison of ipsilateral and contralateral rate of change (ROC) of auditory acuity at different frequencies between the carotid endarterectomy (CEA) group and medicine group. The ROC of auditory acuity at a certain frequency was defined as [(pretreatment auditory acuity − post-treatment auditory acuity)/pretreatment auditory acuity]. The bars above the zero line indicate improvement of auditory acuity and below the zero line means impairment. A, Ipsilateral auditory acuity: the asterisks indicate that the ROCs at all frequencies (250 Hz, 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz) were significantly different between the two groups. B, ROCs of contralateral auditory acuity at frequencies of 1000 Hz, 2000 Hz, and 4000 Hz were significantly different, as indicated by asterisks.

Fig 2 Comparisons of the rate of change (ROC) between the carotid endarterectomy (CEA) group and the medicine group on three scales. The asterisks indicate a significant difference. The ROC was defined as [(post-treatment value − pretreatment value)/pretreatment value]. For Mini Mental State Examination (MMSE) and the Barthel Index of Activities of Daily Living (Barthel), the bars above the zero line indicate improvements, and for National Institutes of Health Stroke Scale (NIHSS), the bars below the zero line mean improvements.

Fig 3 Cross-time change in the Mini Mental State Examination (MMSE) in the carotid endarterectomy (CEA) group. The full marks of MMSE scale are 30, and higher marks indicate better cognitive function. The asterisks indicate that the difference of MMSE scores between two time points is significant.
