Data Description

The WOMAN trial was a large, pragmatic, randomised, double blind, placebo controlled trial to quantify the effects of the early administration of tranexamic acid on death, hysterectomy and other relevant outcomes. This dataset includes the data for 20,060 adult women, who had clinically diagnosed postpartum haemorrhage and who fulfilled the eligibility criteria, who were randomised to receive either TXA or placebo.

Relevant data on an entry form was collected before randomisation to assess eligibility and then the woman was randomised. Outcome data was completed at death, discharge from the randomising hospital or 6 weeks (42 days) after randomisation, whichever occurred first. Each row in the dataset represents the full entry and outcome data collected for one woman. Additional information was collected on the sequence of events leading to death to confirm the cause of death.

Data Collection Methods

This trial was coordinated from LSHTM and conducted in hospitals from 21 countries worldwide. Data was collected at each site by local investigators and transmitted to the CTU either as a paper form (by fax or email) or by entering the data directly into the trial database. Data outlined on the entry, outcome and adverse event forms was collected for this trial. The data was collected from the woman’s and her baby/ies routine medical records; no special tests were required.

Geographic regions

The trial was a global collaboration, conducted in 193 hospitals across 21 countries.
