Fig. 2: The CNI scores of ctDNA in 26 patients with dynamic plasma samples.

a The CNI scores of ctDNA in plasmas and paired blood cells from 26 AGC patients. b The CNI scores of ctDNA from plasma samples before and after treatment in 26 AGC patients. c The CNI scores of ctDNA from plasma under different clinical responses. CNI score copy number instability score, PR partial response, SD stable disease, PD progressive disease. All data are presented as mean ± SD. P < 0.001 according to t test or one-way ANOVA. d The dynamic changes of CNI scores and tumor biomarkers during the administration of treatments in four patients
