Overall maternal mortality ratios do not include late maternal deaths.
Rate ratios and rate differences express change in maternal mortality ratios between 1993 and 2014.
CI denotes confidence interval, APH antepartum hemorrhage and PPH refers to postpartum hemorrhage. Other sp. pregnancy conditions refers to other specified pregnancy related conditions including pregnancy related renal disease, exhaustion, fatigue and peripheral neuritis (O26.8).
