Fig. 1From: Molecular biomarkers screened by next-generation RNA sequencing for non-sentinel lymph node status prediction in breast cancer patients with metastatic sentinel lymph nodesDistribution of sequencing base quality. a Base quality of paired-end reads for NSLN negative group. b Base quality of paired-end reads for NSLN positive group. The base quality of sequencing reads was greater than 25 in five samples except for 67167 whose base quality was slightly lower (≥20)Back to article page
