Data are presented as mean±sd unless otherwise stated and were analysed using the Mann–Whitney test. p-Values less than 0.05 were deemed to represent significant difference. AD: Alzheimer's disease; DLB: dementia with Lewy bodies; Cx: lowest concentration of inhaled citric acid that could induce ≥x coughs; Cu: concentration of citric acid at a threshold of UTC; UTC: urge-to-cough.
