Differences in years of education were marginally significant ( P =.055), with Hispanic decedents (median = 13 years) and black decedents (14 years) observed to have the lowest years of education compared with white decedents (14 years).
Although the observed numerically lower frequency of APOE ε4 among Hispanic decedents relative to black decedents and white decedents did not reach statistical significance, other studies have demonstrated lower APOE ε4 frequency in Hispanic individuals affected by AD [ 6 , 16 , 18 , 19 ].
Differences in the length of education approached significance, suggesting that Hispanic decedents and black decedents had fewer years of education than white decedents is consistent with the 2015 United States Census data, showing that white decedents are more likely to have 16 or more years of education compared with Hispanic decedents and black decedents [ 40 ].
