^*Statistically significant at p < 0.05
^aAdequate knowledge was defined as being able to recall three or more obstetric danger signs during pregnancy, delivery and childbirth
^bAdequate knowledge was defined as being able to recall three or more birth preparedness and complication readiness (BPCR) components
^cLocation of delivery (home vs. health facility); health facility was used as an indicator of institutional birth rate as trained health workers do not conduct deliveries outside the health facility in these areas
