Table 1 Baseline characteristics and stillbirths of women in the WOMAN trial who survived, and of the women who died. The second and third columns report the number of women in each category and the corresponding percentage. The fourth and fifth columns report the odds ratios, and the P values calculated from the likelihood ratio test

From: The WOMAN trial: clinical and contextual factors surrounding the deaths of 483 women following post-partum haemorrhage in developing countries
