Multivariate analysis of relationship between presence of GI symptoms ^† and various parameters associated with FGIDs

Parameters	Crude odds ratio (95% CI)	Crude P values	Adjusted odds ratio (95% CI)	Adjusted P values (LR test)
Presence of GI symptoms (reference: no GI symptom)
GI symptoms with or without anorexia	6.0 (1.9–19.1)	0.002	0.2 (0.03–1.8)	0.01
Anorexia only	8.4 (2.5–28.9)	<0.001	2.8 (0.4–21.1)	0.6 ‡
Anosmia (yes vs no)	3.5 (1.5–7.9)	0.003	2.4 (0.6–10.5)	0.09
Ageusia (yes vs no)	2.7 (1.2–6.2)	0.01	2.1 (0.4–10.2)	0.09
Severity of COVID‐19 (reference, asymptomatic and mild) §	19 (3.79,95.13)	<0.001	12.18 (0.29,506.72)	0.02
Either CBD, dyspeptic symptoms or both at 1‐mo (yes vs no)	67.2 (20.9–214.9)	<0.001	18.4 (3.8–88.7)	<0.001
Either CBD, dyspeptic symptoms or both at 3‐mo (yes vs no)	86.5 (26.4–283.3)	<0.001	36.6 (6.5–206.2)	<0.001

CBD, chronic bowel dysfunction; CI, confidence interval; COVID‐19, coronavirus disease‐19; FGID, functional gastrointestinal disorders; GI, gastrointestinal; LR, likelihood ratio.

^† Because anorexia is a common and non‐specific symptom during any viral illness, those who had anorexia as the only GI symptom (n = 48, 17%) were separately grouped.

^‡ Wald's test.

^§ For the purpose of comparison, asymptomatic and mild were grouped together; moderate and severe were grouped together.
