From: Prediction of P-tau/Aβ42 in the cerebrospinal fluid with blood microRNAs in Alzheimer’s disease
The levels of Aβ42 and P-tau in the cerebrospinal fluid of cognitively normal controls and patients with Alzheimer’s disease (AD). The cutoff value of P-tau/Aβ42 (0.14) was used to determine AD in Dataset 1 (a), 2 (b), 3 (c), and 4 (d). Dotted line: slope = 0.14 indicates the cutoff value of P-tau/ Aβ42; 500 pg/ml in horizontal axis indicates the cutoff value of Aβ42. Abbreviations: AD, Alzheimer’s disease; VaD, vascular dementia; PDD, Parkinson disease dementia; bvFTD, behavioral variant frontotemporal dementia; DLB, dementia with Lewy body
