- Analyses with linear mixed models with zonulin changes as dependent variable, and patient as random effect. The fixed effects are sex, age, body mass index, intervention period (with the intervention period given in the heading of the column as reference), the explanatory variable in the same row and the interaction between this explanatory variable and the intervention period. The interaction terms between the intervention period and the explanatory variable in the same line are also presented separately in the columns to the right with title “Interaction”
