Fig. 2From: Urogenital Microbiota:Potentially Important Determinant of PD-L1 Expression in Male Patients with Non-muscle Invasive Bladder CancerAlpha Diversity and Alpha rarefaction curves for PD-L1-positive (group P) and PD-L1-negative groups (group N). Ace index (A), observed species (B), Chao1 index (C), Shannon index (D) and Simpson index (E) were used for the assessment of alpha diversity between group P and group N. Rarefaction curves show that the Richness of group P was much higher than that of group N (F)Back to article page
