FIG. 3.

Associations between stool SCFAs and hand grip strength. Linear regression models with interaction terms between HIV and levels of stool SCFAs were conducted to determine estimates for physical function or body mass change for each 1 unit increase in SCFA levels. A Forest Plot was created to display the estimate (β) and 95% CI for associations between increasing levels of stool butyrate, propionate, or acetate and hand grip strength. Estimates >1 indicate associations between increasing SCFA levels and greater hand grip strength. SCFAs, short chain fatty acids.
