  3. Table 5 shows adjusted relative risk ratios from multivariable multinomial logistic regression assessing the association of socioeconomic, biological, and psychosocial factors with reported obstetric complications and near misses (compared to 30,450 non-complicated pregnancies) among 41,660 married women of reproductive age with data on all independent variables in rural northwest Bangladesh from December 2007 to June 2011. Results are adjusted by year and season of pregnancy outcome.
