  1. The table shows the results of multivariable linear regression analyses in terms of the unnormalized regression coefficients as well as 95%-confidence intervals. The level of significance was set at p < 0.05. *Indicator variable with values 0 and 1 for ages < and ≥ 60 years of age, respectively. CRP values were included as log10-transformed values, therefore the respective coefficient must be interpreted as change in the respective DemTect score for a tenfold increase in CRP level (log10(10) = 1).
