aFrom the 55 patients of the study and control group, each one, in 39 and 6 patients it was possible to quantify the number of colonies and yeasts species, respectively.
bStatistically significant at the level P < 0.05 for number of colonies (Pearson's Chi-Square test).
cNot statistically significant at the level P > 0.05 for yeast species (Pearson's Chi-Square test).
