Population: different dementias considered in the diagnosis. Method: quantitative method applied in the study. Cohort investigated: number of patients considered for sensitivity and specificity estimations in the discrimination. Sensitivity and specificity: results of the study data show potential of discrimination. LHR+: likelihood ratio. Increase in the LHR+: increase in the probability of the likelihood of the disease. GRADE: results of GRADE evaluation. Quality of evidence was evaluated based on LHR+ values, LHR+ increase probability, and size of the sample included.

Abbreviations: AD: Alzheimer's disease; LBD: Lewy body dementia; FTD: frontotemporal dementia; HC: healthy controls.
