Randomized Controlled Trial Clinical Trial
Clinical predictors of hypoxaemia in Gambian children with acute lower respiratory tract infection: prospective cohort study.
To determine clinical correlates and outcome of hypoxaemia in children admitted to hospital with an acute lower respiratory tract infection. ⋯ In children with an acute lower respiratory tract infection, simple physical signs that require minimal expertise to recognise can be used to determine oxygen therapy and to aid in screening for referral. The association between hypoxaemia and death highlights the need for early recognition of the condition and the potential benefit of treatment.

Multicenter Study Clinical Trial Controlled Clinical Trial
Migraine and stroke in young women: case-control study. The World Health Organisation Collaborative Study of Cardiovascular Disease and Steroid Hormone Contraception.
To investigate the association between migraine and ischaemic or haemorrhagic stroke in young women. ⋯ Migraine in women of childbearing age significantly increases the risk of ischaemic but not haemorrhagic stroke. The coexistence of oral contraceptive use, high blood pressure, or smoking seems to exert a greater than multiplicative effect on the risk of ischaemic stroke associated with migraine.
