FIGURE 5.

Diet effects on cognition. Diet affected cognition differently for normal cognition (NC) and mild cognitive impairment (MCI) groups (diet x diagnosis x time F_[1,71] = 4.00, P = .049). No individual comparisons between groups achieved significance; the NC group's scores tended to improve for the Mediterranean diet (Med‐diet) and remain unchanged for the Western diet (West‐diet; P = .077), whereas the MCI group scores were unchanged. Figures depict change scores for ease of interpretation, adjusted means from repeated measures analysis of covariance are included in Table S2. Error bars represent ± 1 standard error from the mean. Significance is set at ⁺ P < .10, *P < .05, ** P < .01, or *** P < .001
