- Vitamin E for intermittent claudication
Cochrane Systematic Reviews, 16-Oct-2008
It is thought that vitamin E may improve tolerance to intermittent claudication (i.e. pain caused by ischaemia in the muscles of the leg during exercise), thereby relieving the pain, through a variety of mechanisms.
- Vitamin E for neuroleptic-induced tardive dyskinesia
Cochrane Systematic Reviews, 4-Oct-2011
Antipsychotic (neuroleptic) medication is used extensively to treat people with chronic mental illnesses. Its use, however, is associated with adverse effects, including movement disorders such as tardive dyskinesia (TD) – a problem often seen as repetiti
- Vitamin E supplementation for prevention of morbidity and mortality in preterm infants
Cochrane Systematic Reviews, 12-Aug-2008
Treating very low birth weight (VLBW) infants with pharmacologic doses of vitamin E as an antioxidant agent has been proposed for preventing or limiting retinopathy of prematurity, intracranial hemorrhage, hemolytic anemia, and chronic lung disease. Howev
- Vitamin E supplementation in people with cystic fibrosis
Cochrane Systematic Reviews, 3-Dec-2014
People with cystic fibrosis are at an increased risk of fat-soluble vitamin deficiency including vitamin E. Vitamin E deficiency can cause a host of conditions such as haemolytic anaemia, cerebellar ataxia and cognitive difficulties. Vitamin E supplementa
- Vitamin E supplementation in pregnancy
Cochrane Systematic Reviews, 22-Mar-2016
Vitamin E supplementation may help reduce the risk of pregnancy complications involving oxidative stress, such as pre-eclampsia. There is a need to evaluate the efficacy and safety of vitamin E supplementation in pregnancy.
- Vitamin K antagonists or low-molecular-weight heparin for the long term treatment of symptomatic venous thromboembolism
Cochrane Systematic Reviews, 11-Sep-2012
People with venous thromboembolism (VTE) are generally treated for five days with intravenous unfractionated heparin or subcutaneous low-molecular-weight heparin (LMWH) followed by three months of vitamin K antagonist treatment. Treatment with vitamin K a
- Vitamin K antagonists versus antiplatelet therapy after transient ischaemic attack or minor ischaemic stroke of presumed arterial origin
Cochrane Systematic Reviews, 14-Jan-2013
People who have had a transient ischaemic attack (TIA) or non-disabling ischaemic stroke have an annual risk of major vascular events of between 4% and 11%. Aspirin reduces this risk by 20% at most. Secondary prevention trials after myocardial infarction
- Vitamin K for improved anticoagulation control in patients receiving warfarin
Cochrane Systematic Reviews, 15-May-2014
Effective use of warfarin involves keeping the international normalised ratio (INR) within a relatively narrow therapeutic range. However, patients respond widely to their dose of warfarin. Overcoagulation can lead to an increased risk of excessive bleedi
- Vitamin K for the primary prevention of cardiovascular disease
Cochrane Systematic Reviews, 21-Sep-2015
A deficiency in vitamin K has been associated with increased calcium deposition and coronary artery calcification, which may lead to cardiovascular disease.
- Vitamin K for upper gastrointestinal bleeding in people with acute or chronic liver diseases
Cochrane Systematic Reviews, 8-Jun-2015
Upper gastrointestinal bleeding is one of the most frequent causes of morbidity and mortality in the course of liver cirrhosis. Several treatments are used for upper gastrointestinal bleeding in people with liver diseases. One of them is vitamin K adminis
- Vitamin K prior to preterm birth for preventing neonatal periventricular haemorrhage
Cochrane Systematic Reviews, 15-Feb-2011
Preterm infants are at risk of periventricular haemorrhage (PVH). This can be a sign of brain damage that might lead to neurodevelopmental abnormalities, including cerebral palsy. It has been suggested that vitamin K might improve coagulation in preterm i
- Vitamin K supplementation for cystic fibrosis
Cochrane Systematic Reviews, 13-Apr-2015
Cystic fibrosis is a genetic disorder which can lead to multiorgan dysfunction. Malabsorption of fat and fat-soluble vitamins (A, D, E, K) may occur and can cause subclinical deficiencies of some of these vitamins. Vitamin K is known to play an important
- Vitamin supplementation for preventing miscarriage
Cochrane Systematic Reviews, 7-Dec-2010
Miscarriage is a common complication of pregnancy that can be caused by a wide range of factors. Poor dietary intake of vitamins has been associated with an increased risk of miscarriage, therefore supplementing women with vitamins either prior to or in e
- Vitamins C and E for asthma and exercise-induced bronchoconstriction
Cochrane Systematic Reviews, 23-Mar-2015
The association between dietary antioxidants and asthma or exercise-induced bronchoconstriction (EIB) is not fully understood. Vitamin C and vitamin E are natural antioxidants that are predominantly present in fruits and vegetables; inadequate vitamin E i
- Vitamins for epilepsy
Cochrane Systematic Reviews, 10-Aug-2009
Vitamins have been reported to be effective in controlling certain types of seizures and to prevent some of the harmful effects of antiepileptic drugs (AEDs). In this review we will summarize evidence from randomized controlled trials.
- Vitrectomy for idiopathic macular hole
Cochrane Systematic Reviews, 11-May-2015
A macular hole is an anatomic opening in the retina that develops at the fovea. Macular holes can be seen in highly myopic eyes or following ocular trauma, but the great majority are idiopathic. Pars plana vitrectomy was introduced to treat full-thickness
- Vitrectomy with internal limiting membrane (ILM) peeling versus vitrectomy with no peeling for idiopathic full-thickness macular hole (FTMH)
Cochrane Systematic Reviews, 21-May-2013
Several observational studies have suggested the potential benefit of internal limiting membrane (ILM) peeling to treat idiopathic full-thickness macular hole (FTMH). However, no strong evidence is available on the potential benefit(s) of this surgical ma
- Vitrification versus slow freezing for women undergoing oocyte cryopreservation
Cochrane Systematic Reviews, 28-Aug-2014
Oocyte cryopreservation is a technique with considerable potential in reproductive medicine, including fertility preservation, as a way of delaying childbearing and as part of oocyte donation programs. Although the technique was relatively ineffective at

Cochrane Systematic Reviews, 11-Oct-2013
Traumatic upper limb injury is a leading cause of work-related disability. After return-to-work (RTW), many survivors of injuries are able to regain a quality of life (QoL) comparable with the normal population. Since RTW plays an important role in econom
