Figure 2 Alpha diversity analysis of microbiota in the six groups. A: The Chao1 index between Group DM and Group C; B: The Shannon index between Group DM and Group C; C: The simpson index between Group DM and Group C; D: The Chao1 index between Group DR and Group D; E: The Shannon index between Group DR and Group D; F: The simpson index between Group DR and Group D; G: The Chao1 index between Group PDR and Group NPDR; H: The Shannon index between Group PDR and Group NPDR; I: The simpson index between Group PDR and Group NPDR. ^aP < 0.05. NS: Not significant. Group C: Samples with non-diabetics; Group DM: Samples with diabetics; Group DR: Samples with diabetic retinopathy; Group D: Samples without diabetic retinopathy; Group PDR: Patients with proliferative diabetic retinopathy; Group NPDR: Patients without proliferative diabetic retinopathy.
