Predictors of IBS and IBS-SSS. The covariates in the logistic and linear regression analyses were group, BDI-II, and IL-10 and TNF in serum and CSF. The results are given as OR (95% CI) and value for the logistic regression analyses and as B (95% CI) and value and partial correlation for the linear regression analyses.
