Biometrical twin modeling. A Univariate biometrical ACE model. A = additive genetic influences, C = common/shared environmental influences, E = unique environmental influences, ramz = correlation within MZ twin pairs, radz = correlation within DZ twin pairs, rc = correlation within MZ and DZ twin pairs. B Bivariate correlated factor model with creatinine and plasma NfL. For simplicity, only one twin is shown for the bivariate model. Genetic (rg), common environmental (rc), and unique environmental (re) correlations between the two biomarkers were estimated
