^a The denominator used to determine the percentage of women with each characteristic varies due to missing data
^b Risk ratios were generated from models evaluating the outcome of women who died vs women who were alive six weeks after delivery. Generalized linear models were used to evaluate the relationship of potential factors and maternal mortality and to develop point and interval estimates of relative risk associated with these factors. Generalized estimating equations were used to account for the correlation of outcomes within cluster to develop appropriate confidence intervals. Unless otherwise noted, the reference group is women who did not have the listed characteristic
