*Crude odds rations (COR) and adjusted odds ratios (AOR) with 95% Confidence Intervals (95% CI) are shown for the odds of having ever experienced physical and/or sexual violence by an intimate partner (IPV), among ever-partner women, in three locations of South Sudan. Figures in bold are statistically significant at the 95% level (confidence interval does not include 1·0).

** Model 1 shows the association between individual independent variables and physical and/or sexual IPV on a pooled data set with adjustment for site only.

***Model 2 is the final multivariate model that includes all significant independent variables, controlling for age and location.

Note: *p < .05 ** = p < .01 *** = p < .001
