^aThe three values for each parameter indicate the magnitude and direction of Pearson correlation, statistical significance of the correlation, and number of samples on which the calculation was based, respectively. Significant values (P < 0.05) are shown in bold. BCVFA, branched chain volatile fatty acids.
