APOE and obstructive sleep apnea syndrome: Fully adjusted models exploring the influence of APOE-e4, OSA, and their interaction on abnormal levels of amyloid while controlling for race, sex, age, and years of education indicated that only age also demonstrated a relationship with abnormal levels of amyloid, and the continued significance of the model suggested that race, sex, years of education, and to a lesser degree age, had no influence on the associations explored (see Table 3 for results of the fully adjusted models).
