The associations between the overall and the total relative abundance of 56 microbial short-chain fatty acid (SCFA) producers with body mass index (BMI) and waist-to-height-ratio (WHtR).
| Overall 1 | Total 2 | |||||
|---|---|---|---|---|---|---|
| n | Mean (SD) | R2 | p-Value | β (95% CI) | p-Value | |
| BMI | 209 | 24.35 (3.21) | 0.008 | 0.05 | −0.04 (−1.7, 1.61) | 0.96 |

The 56 microbial SCFA producers were selected from literature and the full list with references is in Table S2. The raw counts of each species and the total counts of the 56 species were normalized and log10 transformed [29]. Model was adjusted for age, sex, province, urbanization, income, education, total energy, insoluble fiber intake, physical activity, smoking, and alcohol intake. 1 R2 and p-value were calculated using permutational multivariate analysis of variance (PERMANOVA) of all 56 species. 2 Linear regression was performed on the total relative abundance of the 56 species.
