Distribution of EGFR mutations between different failure sites. a The proportion of ARMS^T790M+ and ARMS^T790M− in different failure sites (left). The proportion of ARMS^19del+T790M, ARMS^L858R+T790M, and ARMS^T790M+ in different failure sites (up-right). The distribution of ARMS^wild-type, ARMS^19del, and ARMS^L858R in different failure sites (down-right). b The proportion of ddPCR^T790M+ and ddPCR^T790M− (left), as well as the abundance of T790M in patients with detectable T790M mutation (up-right) and in total patients (down-right).
