Fig. 3: Correlation between gut microbiota and muscle function.

Pearson’s correlation analysis between the abundance of the core microbiome and grip strength (a, r = 0.807, p < 0.0001,95%CI of x-intercept 66.3–108.3), soleus muscle weight (b, r = −0.721, p < 0.001,95%CI of x-intercept 0.0058–0.0075), and gastrocnemius muscle weight (c, r = −0.786, p < 0.0001,95%CI of x-intercept 0.14–0.16) in mice (20 mice) at week 8. d Pearson’s correlation coefficient (r) for the correlation between core microbiome and grip strength, soleus muscle weight, and gastrocnemius muscle weight. Correlation plot with confidence interval set at 95% (Light green shadowed area).
