P’: Comparison between both groups before treatment. Group 1: Low fermentable oligo, di- and monosaccharides and polyols (FODMAP) diet + probiotic, Group 2: low fermentable oligo, di- and monosaccharides and polyols diet + placebo. VAS: Visual analogue scale; IBS-SSS: Irritable bowel syndrome symptom severity scale; IBS: Irritable bowel syndrome; SD: Standard deviation.
