Summary statistics for the multiple linear regression model assessing the relationship between inflammatory proteins and brain MRI measures (whole brain volume and left entorhinal cortex).

The relationship between cytokines and MRI measures was assessed by multiple linear regression adjusting for age, gender, collection site and presence of the APOε4 allelle. Whole cohort result shows the model overall data and was based on all three diagnostic groups with 239 subjects for TNF-α and 241 subjects for IL-13.
Key: Beta = regression coefficient (slope) on transformed data; CI = 95% confidence interval; R2 = R2 value (coefficient of determination) after adjusting for covariates;
*p<0.05; W indicates whole brain volume (normalized to Intracranial Volume (ICV)); E indicates left entorhinal cortex(normalized to Intracranial Volume (ICV)).
