Journal ArticleDOI
Risks of stroke and mortality associated with suboptimal anticoagulation in atrial fibrillation patients.
Arlene M. Gallagher,Efrosini Setakis,Jonathan M. Plumb,Andreas Clemens,Tjeerd-Pieter van Staa +4 more
TL;DR: Good anticoagulation control was associated with a reduction in the risk of stroke and Mortality rates were significantly lower with at least 70% of time spent within therapeutic range.
Journal ArticleDOI
Use of statins and risk of fractures.
TL;DR: Use of statins at dosages prescribed in clinical practice was not associated with a reduction in risk of fracture, and use of statin dosage less than 20 mg/d (standardized to simvastatin) was associated with an adjusted OR of fracture.
Journal ArticleDOI
The opportunities and challenges of pragmatic point-of-care randomised trials using routinely collected electronic records: evaluations of two exemplar trials.

Torgerson,Sarah Ronaldson,Joy Adamson,Adel Taweel,Brendan Delaney,Samhar Mahmood,Simona Baracaia,Thomas Round,Robin Fox,Tommy Hunter,Martin Gulliford,Liam Smeeth +19 more
TL;DR: EHR point-of-care trials are feasible, although the recruitment of clinicians is a major challenge owing to the complexity of trial approvals, and Good Clinical Practice guidelines, governance and consent procedures were found to have substantially affected the intended simple nature of the trials.
Journal ArticleDOI
Prediction of Cardiovascular Risk Using Framingham, ASSIGN and QRISK2: How Well Do They Predict Individual Rather than Population Risk?
TL;DR: Application of existing CVD risk scores may result in considerable misclassification of high risk status, and current practice to use a constant threshold level for intervention for all patients, together with the use of different scoring methods, may inadvertently create an arbitrary classification of high CVDrisk.
Journal ArticleDOI
Use of Statins and Risk of Fractures
TL;DR: In this paper, a statin dosage of less than 20 mg/d (standardized to simvastatin) was associated with an adjusted OR of fracture of 1.13 (95% CI, 0.96-1.33).
