Associations between exposure to oral cholera vaccine (OCV) and occurrence of adverse pregnancy outcomes in Dhaka, Bangladesh.

	Exposed to OCV (cases/total samples)	Non-exposed to OCV (cases/total samples)	Odds ratio (95% CI)	p-Value
Model 1	11/65	8/69	1.63 (0.58–4.77)	0.36
Model 2	15/69	8/69	2.28 (0.87–6.44)	0.10
Model 3	11/65	8/69	0.45 (0.11–1.88)	0.27
Model 4	15/69	8/69	0.59 (0.15–2.34)	0.22

Model 1: Adverse pregnancy outcome (without induced abortion) was modeled on the exposure to OCV adjusted for propensity score^a.

Model 2: Adverse pregnancy outcome (including induced abortion) was modeled on the exposure to OCV adjusted for propensity score^a.

Model 3: Adverse pregnancy outcome (without induced abortion) was modeled on the exposure to OCV adjusted for propensity score^b.

Model 4: Adverse pregnancy outcome (including induced abortion) was modeled on the exposure to OCV adjusted for propensity score^b.

^aPropensity score includes age at zero time, education, sanitary toilet use, sharing of kitchen with other household(s) and having one or more children prior to the index pregnancy.

^bPropensity score additionally includes gestational age at zero time.
