From: Transcriptome analysis of bacteriophage communities in periodontal health and disease
Bar plots (± standard deviation) of phage genes expressed in relative periodontal health (white bars) or significant periodontal disease (black bars). Each functional category of genes is indicated on the x-axis and the percentage of total viral genes expressed is demonstrated on the y-axis. P-values that are  < 0.05 are represented by the '*' and represent comparisons between subjects with periodontal health and disease
