Fig. 1From: Detection and recognition thresholds for five basic tastes in patients with mild cognitive impairment and Alzheimer’s disease dementiaResults of gustatory tests in patients with Alzheimer’s disease dementia (ADD), mild cognitive impairment (MCI), and non-demented controls (NDCs). The recognition threshold (RT) of patients with ADD exhibited a significant increase compared with those in NDCs. However, detection threshold (DT) and RT minus DT (RT − DT) was not significant among three groups. The DT was compared by an analysis of covariance with age as a covariate followed by the Bonferroni correction. The RT and RT − DT were compared by the Kruskal–Wallis test followed by the Bonferroni correction. All data are indicated by box-and-whisker plots following the Tukey method (*p < 0.05)Back to article page
