Fig. 2

Venn diagrams of common and distinct taxa between the two study groups (DB group and healthy control group) at the phylum level (a) and genus level (b). The overlapping part of b represents the shared components of the DB group and the healthy control group; the non-overlapping part represents the unique components in each group. The red part of the diagram represents the control group (eyelashes from healthy volunteers); the blue part of the diagram represents the DB group (eyelashes from patients with Demodex blepharitis); and the brown part of the diagram represents overlap between the two groups (i.e. genera common to both study groups)
