CRP and Alzheimer disease: Sodium levels (RR: 2.564, (95% CI: 2.478, 2.653)), blood glucose levels (RR: 2.556, (95% CI: 2.471, 2.644)), and CRP levels (RR: 2.505, (95% CI: 2.431, 2.580)) were associated with the highest risk for AD when matching with age (all p < 0.001), but the risk was not significantly higher than in the unmatched cohorts.
