Strengths and Limitations
Limitations of this study are its retrospective nature and the small number of patients. Including dehiscence cases caused the groups to be heterogeneous in terms of gravity, parity and maternal age. However, none of these variables were significant in the regression analysis, showing that infection is well-correlated with uterine rupture. The average gestational age, was younger in the study group compared to the controls and birth weights were smaller. We believe this may be due to symptoms of rupture that developed earlier and led to an emergent CD. A COS was used, because there is no relevant core outcome in the database. Uterine rupture might be an important addition to the core outcomes.
