Irritable bowel syndrome-severity score system (IBS-SSS) outcome adjusted for baseline covariates: gender, age at diagnosis, smoking status, IBS subtype, surgery, medication, disease duration and body mas index (BMI). IBS duration, baseline IBS-SSS and treatment modality were used as regression variables ± 95%CI: Lower-upper). LFD: Low fermentable, oligosaccharides, disaccharides, monosaccharides and polyols diet; LGG: Lactobacillus rhamnosus GG; ND: Normal (Danish/Western) diet; Diff SSS: IBS-SSS difference.
