Table 3: Predictors for “treatment effect” (increase in symptoms during active treatment minus increase during placebo treatment).

Independent variables		values

Active treatment	3.03–3.20	–0.035
Bacteroides	1.59	ns ()
Faecalibacterium	−0.02	ns ()
Lachnospiraceae	−1.39	ns ()
“Common” Simpson’s D	−0.39	ns ()

The table gives the results of four linear regression analyses. “Treatment effect” is a dependent variable, and treatment is an independent variable in all analyses; changes in Simpson’s diversity score and the proportions of Bacteroides, Faecalibacterium, and Lachnospiraceae are independent variables in each of the four analyses.
