Furthermore, adjusted multiple regression stratified for both diagnostic classification and APOE-ε4 status showed that the effect of high hs-CRP on poorer executive function was specific to APOE-ε4 non-carriers with SCD (β[95% CI] = −.31[−1.06, −.12], p = .014, n = 87). Here, APOE is linked to Schnyder corneal dystrophy.
