ALB and Lewy body dementia: Polytomous logistic regression analysis adjusting for age among the three diagnostic groups showed that DLB and FTLD patients were 7.2 times and 10.1 times more likely, respectively, to have low serum albumin than AD patients (DLB: Wald = 4.983, p = 0.026; FTLD: Wald = 4.014, p = 0.045).
