Analysis of the presence/absence of the apoE4 isoform in two cohorts of 230 (study cohort) and 50 (validation cohort) plasma samples by ELISA or by a turbidimetric assay based on LEIT. (A) Analysis of the presence of apoE4 in the study cohort of 230 plasma samples by ELISA setup stratified by APOE genotype. (B) Analysis of the presence of apoE4 in the validation cohort of 50 plasma samples by ELISA stratified by APOE genotype. (C) Analysis of the presence of apoE4 in the validation cohort of 50 samples by a turbidimetric assay stratified by APOE genotype. Error bars represent median with interquartile range.
