3. Figure 2 Alzheimer's disease to control ratio for CSF T-tau
CSF ratios of T-tau concentrations between patients with Alzheimer's disease and controls. Individual study ratios and their corresponding 95% CIs are indicated by filled squares. The size of the square indicates the weight of the study. The averaged ratio and 95% CI is indicated by a diamond. The solid line indicates a ratio of one and the dotted line indicates the average ratio. Arrowheads indicate values in excess of 5. *Number of patients or controls.

CSF ratios of P-tau concentrations between patients with Alzheimer's disease and controls. Individual study ratios and their corresponding 95% CIs are indicated by filled squares. The size of the square indicates the weight of the study. The averaged ratio and 95% CI is indicated by a diamond.

Alzheimer's disease to control ratio for CSF markers of neurodegeneration, glial activation, and blood–brain-barrier function
CSF ratios of NFL (A), NSE (B), VLP-1 (C), HFABP (D), YKL-40 (E), GFAP (F), MCP-1 (G), and CSF to serum albumin ratio (H) between patients with Alzheimer's disease and controls. Individual study ratios and their corresponding 95% CIs are indicated by filled squares. The size of the square indicates the weight of the study. All average ratios and their corresponding 95% CIs are indicated by diamonds. Arrowheads indicate values in excess of 5. *Number of patients or controls.

Biomarker performance rating in patients with Alzheimer's disease versus controls
Head-to-head biomarker performance in CSF (A) and in serum and plasma (B) based on average Alzheimer's disease to control ratios. Biomarkers shown in green are significant with good effect sizes, in purple significant with moderate effect sizes, and in red non-significant or significant with minor effect sizes. The Alzheimer's disease to control ratios of CSF Aβ42, Aβ40, and Aβ38 were inverted to allow for a clear comparison with the other biomarkers.
