Data are presented as mean±sd unless otherwise stated and were analysed using one-way ANOVA (p-values) or using two-way ANOVA when adjusting for gender (p1-values). Values are in bold show where significant differences were expressed (p<0.05 or p1<0.05). AD: Alzheimer's disease; DLB: dementia with Lewy bodies; BMI: body mass index; MMSE: mini mental state examination; FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; PaO2: arterial oxygen tension; PaCO2: arterial carbon dioxide tension.
