Data are presented as mean±sd and were analysed using one-way ANOVA (p-values) or using two-way ANOVA when adjusting for gender (p1-values). Values in bold show where significant differences were expressed (p<0.05 or p1<0.05). 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.
