FIG 3.

Differences in relative abundances of taxa exist between healthy and cancer patients. The top panels show the bacteria that had statistically significant higher relative abundances in healthy patients than in those with cancer (i.e., normal adjacent tissue), and the bottom panels shows the bacteria that had statistically significant higher relative abundances in cancer patients than in healthy controls. The box in each graph signifies the 75% (upper) and 25% (lower) quartiles and thus shows where 50% of the samples lie. The black line inside the box represents the median. The whiskers represent the lowest datum still within 1.5 interquartile range (IQR) of the lower quartile and the highest datum still within 1.5 IQR of the upper quartile. Outliers are shown with open circles. Significance was based on the Benjamini-Hochberg corrected P value of the Wilcoxon rank test (significance threshold, P < 0.1).
