Efficacy of 0.5% Levofloxacin and 5.0% Povidone-Iodine Eyedrops in Reducing Conjunctival Bacterial Flora: Metagenomic Analysis

Figure 2

The principal coordinate analysis was derived from weighted UniFrac distances of 16S rRNA gene between microbial communities of the three groups. Values in parentheses on the axis labels indicate that the percentage variation accounts for each axis. (a) The samples were clustered based on different drug interventions. (b) Groups 1 and 2 were a continuum, and there was little distinction between these two groups. (c, d) There was significant difference between group 3 and the other two groups.
