MDS, multidivisional scaling. Centroids illustrate the 95% CI for the
mean location of each SBP (mmHg) quartile. Vectors for 10 taxa with the greatest
contributions to MDS4 indicate the directions and strengths of their
correlations with MDS4 (Table
S1). In permutational multivariate analysis of variance (PERMANOVA,
n=1003), SBP had R2 of 0.20% and p-value of 0.002, after adjusting
for age, sex, provinces, urbanization index (≤64.2, 64.2–81.5,
>81.5), per-capita household income (≤10, 10–21.6,
>21.6), education, total energy intake, animal-source food, sodium,
physical activity (≤57.4, 57.4–152, >152), smoking,
alcohol, and estimated glomerular filtration rate (eGFR). Results remained the
same after additional adjustment of BMI.
