Abdominal bloating sites in different FGIDs. Results are given as odds ratios^* (95% CI)

	Upper site vs general abdomen	Lower site vs general abdomen	Lower site vs upper site
Female	0.5 (0.3 to 0.7)	2.1 (1.4 to 3.4)	4.6 (2.9 to 7.4)
IBS†	0.7 (0.3 to 1.4)	2.1 (1.1 to 4.0)	3.2 (1.5 to 6.8)
Dyspepsia†	5.8 (1.5 to 22.4)	1.5 (0.3 to 7.8)	0.3 (0.1 to 1.03)
FC†	0.8 (0.3 to 1.9)	2.6 (1.3 to 5.4)	3.3 (1.4 to 7.7)
GORD†	1.2 (0.6 to 2.3)	1.3 (0.7 to 2.6)	1.1 (0.5 to 2.3)
GI complex overlap‡	0.9 (0.5 to 1.7)	0.6 (0.4 to 1.1)	0.7 (0.4 to 1.3)

^*Multiple variable logistic models adjusted for age and SSC score.

^†IBS, dyspepsia, FC and GORD were cases with no GI complex symptom overlap.

^‡GI complex overlap: subjects can be defined as more than one of the above disorders.

FC, functional constipation; FGIDs, functional gastro-intestinal disorders; GI, gastro-intestinal; GORD, gastro-oesophageal reflux disease; IBS, irritable bowel syndrome; SSC, Somatic Symptom Checklist.
