All associations between Olink Biomarkers and the dementia outcome in this table are statistically significant after correction for multiple testing (FDR corrected p < 0.05). The lines for the most important biomarkers, EN-RAGE and LAP TGF-beta-1, which were also independently from other Olink biomarkers associated with the dementia outcome, are printed in bold. However, please note that this table shows their association with the outcome when they are put singularly in the multivariate logistic regression model
* Multivariate logistic regression model adjusted for age (continuously), sex, education, physical activity, BMI (categorical), CVD, diabetes, depression, APOE genotype
