Cognitive performance dependent on familial longevity (offspring versus partner status*).

*Offspring = 0, partner = 1.†Values are expressed as mean (standard error).‡n = 223 for offspring and n = 223 for partners. Abbreviations: β, estimate; CI, confidence interval; 15-PLT, 15-Picture Learning Test; DSST, Digit Symbol Substitution Test. Model 1: adjusted for age, gender and years of education. Model 2: as model 1+ diabetes mellitus, cardiovascular diseases (myocardial infarction, stroke and hypertension), alcohol use, smoking, high-sensitivity C-reactive protein, interleukin-6 and apolipoprotein E genotype. Robust standard errors were used to account for familial relationships among the offspring.
