Randomized Controlled Trial Multicenter Study Clinical Trial
Effect of Hypericum perforatum (St John's wort) in major depressive disorder: a randomized controlled trial.
Extracts of Hypericum perforatum (St John's wort) are widely used for the treatment of depression of varying severity. Their efficacy in major depressive disorder, however, has not been conclusively demonstrated. ⋯ This study fails to support the efficacy of H perforatum in moderately severe major depression. The result may be due to low assay sensitivity of the trial, but the complete absence of trends suggestive of efficacy for H perforatum is noteworthy.

Randomized Controlled Trial Clinical Trial
Outcomes at 3 months after planned cesarean vs planned vaginal delivery for breech presentation at term: the international randomized Term Breech Trial.
The Term Breech Trial found a significant reduction in adverse perinatal outcomes without an increased risk of immediate maternal morbidity with planned cesarean delivery compared with planned vaginal birth. No randomized controlled trial of planned cesarean delivery has measured benefits and risks of postpartum outcomes months after the birth. ⋯ Planned cesarean delivery for pregnancies with breech presentation at term may result in a lower risk of incontinence and is not associated with an increased risk of other problems for women at 3 months post partum, although the effect on longer-term outcomes is uncertain.
