도 2는 검증 세트(validation set)에서, 정상 대조군("Normal"), 아밀로이드 병리소견이 없는 경도인지장애 환자군("MCI(non-AD)"), 알츠하이머병 경도인지장애 환자군("Prodromal AD"), 및 알츠하이머병 치매 환자군("Symptomatic AD")에서 ATP2C1 유전자 프로모터의 DNA 메틸화 정도의 차이를 나타낸 것이다.
도 3은 ATP2C1 유전자 프로모터의 DNA 메틸화 변화를 이용하여 정상 대조군("Normal"), 아밀로이드 병리소견이 없는 경도인지장애 환자군("MCI(non-AD)") 및 알츠하이머병 경도인지장애 환자군("Prodromal AD") 대비 알츠하이머병 치매 환자군("Symptomatic AD")을 구별할 수 있는 유효성을 평가하기 위한 리시버-작동 특징 커브(ROC curve: receiver operating characteristics curve) 분석 결과를 나타낸 것이다.
