Differences in richness, diversity and community structure associated with conjunctival scarring. (A,B) Boxplots indicate distribution of richness and Shannon diversity measures in participants aged >10years with conjunctival scarring (C > 0) versus those with normal conjunctivae (F0P0C0) sampled in the dry (A) and wet (B) seasons; P-values calculated using Wilcoxon rank sum test. (C,D) MDS was used to visualize differences in community structure between all participants aged >10years with scarring (C > 0, filled circles) versus those with normal conjunctivae (F0P0C0, open circles) sampled during the dry season (C) and all participants aged >10years with conjunctival scarring (C > 0, filled circles) versus those with normal conjunctivae (F0P0C0, open circles) sampled during the wet season (D); P-values generated by PERMANOVA.
