Variation in abundance percentages of Bacteroidetes and Firmicutes in relationship to BMI categories
| Normal‐underweight Group (p‐value) | Overweight‐obese group (p‐value) | |
|---|---|---|
| ≥70% | [p = .926] | [p = .735] |
| ≥60% | [p = .490] | [p = .741] |
| ≥50% | [p = .405] | [p = .759] |
| ≥40% | [p = .016]a | [p = .753] |
| ≥30% | [p = .617] | [p = .654] |
| ≥20% | [p = .200] | [p = .567] |
| ≤19.99% | [p = .311] | [p = .046]a |
Individual ANOVA tests comparing the total percentages of B‐F abundance were used to determine variation in prevalence between the two phyla at stratified percentages in relation to BMI categories of normal‐underweight and overweight‐obese.
Only two tests were of significance. The first among the normal‐underweight group [f(1)=8.73; p = .02], with a greater percentage of Firmicutes at the ≥40% range. The second test [f(1)=6.26; p = .05], showing greater percentage of Firmicutes at the ≤19.99% range among the overweight‐obese group.
