1 The Diversity of Gut Microbiome is Associated With Favorable Responses to Anti– Programmed Death 1 Immunotherapy in Chinese Patients With NSCLC  Yueping Jin, MD, PhD, Hui Dong, PhD, Liliang Xia, PhD, Yi Yang, MD, Yongqiang Zhu, MS, Yan Shen, BS, Huajun Zheng, PhD, Chengcheng Yao, MS, Ying Wang, PhD, Shun Lu, MD, PhD  Journal of Thoracic Oncology  Volume 14, Issue 8, Pages (August 2019) DOI: /j.jtho Copyright © 2019 International Association for the Study of Lung Cancer Terms and Conditions

3 Figure 2 Comparison of gut microbiota diversity between responder (R) and nonresponder (NR) groups. (A,B) Shannon index and Inverse Simpson index in R (n = 13) and NR (n = 12) at baseline (A) and T1 timepoint (B), respectively. Statistical analysis was performed by Mann-Whitney test. **p < 0.01, * p < (C) Kaplan-Meier (K-M) plot of the progression-free survival (PFS) by Log-rank test in patients with high diversity and low diversity (Shannon cutoff value: 2.31). (D) Principal coordinates analysis of gut microbiota at baseline. Red legends represented NR and blue legends represented R. Statistical analysis was performed by multivariate analysis of variance test. p = Journal of Thoracic Oncology  , DOI: ( /j.jtho ) Copyright © 2019 International Association for the Study of Lung Cancer Terms and Conditions

4 Figure 3 Comparison of gut microbiota composition between responders (R) and nonresponders (NR). (A) Heatmap of seven bacterial genera with statistically differential abundance in R (n = 13) and NR (n = 12) at baseline. (B) Histogram of two representative differentially abundant genera at baseline. (C) Histogram of Bifidobacterium longum and Prevotella copri at baseline (left) and T1 timepoint (right). Statistical analysis was performed by Mann-Whitney test. **p < 0.01, * p < 0.05.

5 Figure 4 Gut microbiota profiles remain stable during the treatment. (A) Dynamics of Shannon diversity index in longitudinal samples (left) and in paired samples at baseline and T1 timepoint (middle) or progression timepoint (right). (Blue dot: responders [R], red dot: nonresponders [NR]). Statistical analysis was performed by Wilcoxon matched-pairs signed rank (middle and right) or Kruskal-Wallis (left) tests. (B) Stacked bar plot of phylogenetic composition at genus level in paired samples (left: baseline, right: progression). (C) Principal coordinate analysis of 10 individuals sampling at different timepoints using unweighted Unifrac distance. Each symbol represented one individual patient. (D,E) Multiple comparison of representative bacteria at phylum (D) and genus (E) levels by Kruskal-Wallis test. p > 0.05 for all tests.

6 Figure 5 Correlation analysis of Shannon diversity index with peripheral immune signatures. (A,B) Spearman correlations between Shannon diversity index and memory CD8+ T cell subsets. (C) Spearman correlations between Shannon diversity index and natural killer (NK) cell subsets. (D) Comparison of immune parameters between high-diversity group and low-diversity group. (black bar: high diversity; grey bar: low diversity). Statistical analysis was performed by Spearman correlation (A, B, and C) or Mann-Whitney (D) tests. **p < 0.01, * p < 0.05.
