Figure 4. Correlation of growth activity of P. gingivalis and F. alocis.

Figure 4

Correlation of P. gingivalis and F. alocis P:G ratios using linear regression (combined initial and non-surgical periodontal therapy re-evaluation appointments). Trendline equation: log(F. alocis P:G ratio) = 0.4302 * log(P. gingivalis P:G ratio) + 0.0527. R2 value: 0.14902. Outliers (greater than 3 standard deviations from the mean) and sample sites in which P:G ratios of only one target organism was generated were removed from analysis. Number of samples (sites with P:G ratios for both microorganisms) included in analysis = 51.
