The inappropriate and inconsistent selection of primary outcomes (POs) in randomised controlled trials (RCTs) and systematic reviews (SRs) can make evidence difficult to interpret, limiting its usefulness to inform clinical practice. ⋯ There is a lack of consistency in the choice and definitions of POs in clinical research related to preterm birth prevention. SRs are more likely to report morbidity and mortality as POs, whereas RCTs tend to use length of gestation. Researchers are urged to review the outcomes reported in RCTs and SRs in their respective areas of interest to highlight discrepancies and facilitate the development of core outcome sets.

Pregnant and postpartum women with severe hypertension are at increased risk of stroke and require blood pressure (BP) reduction. Parenteral antihypertensives have been most commonly studied, but oral agents would be ideal for use in busy and resource-constrained settings. ⋯ Oral nifedipine, and possibly labetalol and methyldopa, are suitable options for treatment of severe hypertension in pregnancy/postpartum.

Annually, 2.6 million stillbirths occur worldwide, 98% in developing countries. It is crucial that we understand causes and contributing factors. ⋯ To build capacity for perinatal death audit, clear guidelines and a suitable classification system to assign cause of death must be developed. Existing classification systems may need to be adapted. Better data and more data are urgently needed.
