Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
WHO antenatal care randomised trial for the evaluation of a new model of routine antenatal care.
We undertook a multicentre randomised controlled trial that compared the standard model of antenatal care with a new model that emphasises actions known to be effective in improving maternal or neonatal outcomes and has fewer clinic visits. ⋯ Provision of routine antenatal care by the new model seems not to affect maternal and perinatal outcomes. It could be implemented without major resistance from women and providers and may reduce cost.

Randomized Controlled Trial Clinical Trial
Frequency and prevention of symptomless deep-vein thrombosis in long-haul flights: a randomised trial.
The true frequency of deep-vein thrombosis (DVT) during long-haul air travel is unknown. We sought to determine the frequency of DVT in the lower limb during long-haul economy-class air travel and the efficacy of graduated elastic compression stockings in its prevention. ⋯ We conclude that symptomless DVT might occur in up to 10% of long-haul airline travellers. Wearing of elastic compression stockings during long-haul air travel is associated with a reduction in symptomless DVT.
