Abstract
Description
도 2는 건강한 개체(대조군)와 폐암 환자 사이의 구강 마이크로바이옴의 차등적인 풍부한 속(genus)을 확인한 결과로서, 각 왼쪽 패널은 Log10으로 변환된 상대적 풍부도 결과이고, 각 오른쪽 패널은 차등적인 풍부한 속의 일반화된 배수 변화 결과이며, a는 모든 폐암 환자와 대조군 사이의 결과이고, b는 비치료 그룹과 대조군 사이의 결과이며, c는 치료 그룹과 대조군 사이의 결과이다 (q < 0.1).
도 3은 구강 마이크로바이옴에 의한 폐암 예측 결과로서, a는 폐암 환자, 치료 그룹, 비치료 그룹 및 대조군 사이를 구별하는 예측 모델의 ROC(Receiver operating characteristic) 곡선이고, b는 예측 모델(Bayesian Ridge)의 정규화된 계수를 나타낸 결과이다 (계수가 상위 5% 및 하위 5%인 속을 표시함).
