*β-coefficient representing the average change per year for trend of MMR per 100 000 live births between 2002 and 2011.
†SE for β-coefficient obtained between 2002 and 2011 with ARIMA.
‡p Value for trend between 2002 and 2011.
ARIMA, Autoregressive Integrated Moving Average; iAMR, induced abortion mortality ratio; MMR, maternal mortality ratio MMR_AO, MMR with any abortive outcome.
