Clinical effectiveness of adding probiotics to a low FODMAP diet: Randomized double-blind placebo-controlled study

Table 8 The relationship between adherence to diet and changes in visual analogue scale and irritable bowel syndrome symptom severity scale scores

Scores	Group 1; adherence to diet		Group 2; adherence to diet
	r	P value	r	P value
VAS	0.226	0.145	0.425	0.005
IBS-SSS	0.226	0.144	0.434	0.004
Pain severity	0.233	0.133	0.253	0.106
Abdominal pain severity	0.298	0.052	0.287	0.065
Abdominal distention severity	0.001	0.995	0.298	0.055
Satisfaction with intestinal habits	0.092	0.557	0.328	0.034
IBS quality of life	0.264	0.088	0.390	0.011

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. The discrepancy between the initial and final values of the evaluated scores (visual analogue scale, irritable bowel syndrome, etc.) was proportioned to the initial value to create a new variable called “percentage change from baseline” ((last value - initial value)/initial value). The correlation of this variable with dietary compliance in two different groups was investigated. The relationship between the improvement in other scores (numerical) and the diet compliance score (numerical) was investigated. The “r” values we received provide us with knowledge about the relationship’s course and power. VAS: Visual analogue scale; IBS-SSS: Irritable bowel syndrome symptom severity; IBS: Irritable bowel syndrome.
