Boxplot representation of the concentrations of the DNA markers in 1 g of individual feces samples.
(A) The human-associated markers in human feces; (B) The pig-associated markers in pig feces. The median (line within the box) and quartiles are represented. Whisker caps represent the maximum and minimum concentrations of the DNA markers. The F statistics and degree of freedom (df) for the ANOVA test were 9.275 and 4, respectively.
