Figure 4. Interval plot of postbiotic strains compared to
placebo for the efficacy outcome in standardized mean difference (SMD)
(a) and safety outcome in relative risk (RR) (b). The plot shows the
strain-specific SMD for efficacy and RR for safety and their respective
95% confidence interval. For SMD, comparisons with negative treatment
effect estimates at the left of the no-effect line (SMD = 0) favor the
postbiotic strain, whereas positive treatment effect measures at the
right favor the reference treatment, placebo. Relative risk and 95% CI
less than 1 is indicative of the superiority of the intervention over
placebo in terms of safety, whereas relative risk and 95% CI greater
than 1 indicate that the treatment intervention is inferior to placebo.
