2. Fig. 1
The age-adjusted overall mean difference in plasma vitamin A (retinol) levels (μmol/L) between AD patients and controls was significant (P < .001) and approximately 20% of the absolute amount in the control subjects. Abbreviations: AD, Alzheimer's disease; CI, confidence interval; REML, restricted maximum likelihood.

3. Fig. 2
The age-adjusted overall mean difference in plasma folate levels (nmol/L) between AD patients and controls was significant (P < .001) and approximately 20% of the absolute amount in the control subjects. Abbreviations: AD, Alzheimer's disease; CI, confidence interval; REML, restricted maximum likelihood.

4. Fig. 3
The age-adjusted overall mean difference in plasma vitamin B12 (cobalamin) levels (pmol/L) between AD patients and controls was significant (P < .001) and approximately 15% of the absolute amount in the control subjects. Abbreviations: AD, Alzheimer's disease; CI, confidence interval; REML, restricted maximum likelihood.

5. Fig. 4
The age-adjusted overall mean difference in vitamin C (ascorbate) levels (μmol/L) between AD patients and controls was significant (P < .001) and approximately 30% of the absolute amount in the control subjects. Abbreviations: AD, Alzheimer's disease; CI, confidence interval; REML, restricted maximum likelihood.

6. Fig. 5
A trend (P = .075) toward lower age-adjusted vitamin D (calcidiol) levels (ng/mL) in AD patients vs controls was observed. We verified that the two studies of Sato et al. [98,99] concerned different AD and control populations. Abbreviations: AD, Alzheimer's disease; CI, confidence interval; REML, restricted maximum likelihood.

7. Fig. 6
The age-adjusted overall mean difference in α-tocopherol/vitamin E levels (μmol/L) between AD patients and controls was significant (P < .001) and approximately 20% of the absolute amount in the control subjects. Vitamin E levels were used uncorrected for cholesterol amounts. Abbreviations: AD, Alzheimer's disease; CI, confidence interval; REML, restricted maximum likelihood.

8. Fig. 7
The age-adjusted overall mean difference in copper levels (μg/dL) between AD patients and controls was not significant. Abbreviations: AD, Alzheimer's disease; CI, confidence interval; REML, restricted maximum likelihood.

10. Fig. 9
A trend (P = .050) toward lower age-adjusted zinc levels (μg/dL) in AD patients vs controls was observed. Abbreviations: AD, Alzheimer's disease; CI, confidence interval; REML, restricted maximum likelihood.
