Table 3

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

Independent variablesStatistics

Active treatment3.03–3.20 –0.035
Bacteroides1.59ns ( )
Faecalibacterium−0.02ns ( )
Lachnospiraceae−1.39ns ( )
“Common” Simpson’s D−0.39ns ( )

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.
