In order to estimate whether the associations between KL-VSHET+ and amyloidosis were confounded by uneven sample size of APOE ε4-carriers and non-carriers as well as by differences in the sex and age of the participant groups, the association analyses were repeated with equal numbers of APOE ε4-carriers (N = 308) and non-carriers (N = 308) matched for age and sex. The gene discussed is APOE; the disease is amyloidosis.
