EDHS-2014	3.37 (3.20–3.60)***		3.46 (3.15–3.80)***
Place of delivery	Public sector		Private sector

EDHS-2008	1.32 (1.16–1.49)***	1.35 (1.13–1.61)**	1.45 (1.33–1.60)***	1.42 (1.25–1.62)***

OR: odds ratio, aOR: adjusted odds ratio (for all covariates under analysis), CI: confidence interval

P-value for the trend was assessed by entering the year of the survey as a continuous variable
