Sally studied Mathematics and Statistics at Reading University and Medical Statistics at the London School of Hygiene and Tropical Medicine. In 1991 she joined the department of General Practice at St. George’s Hospital Medical School, as one of the first statisticians to specialise in primary care. During this time she developed an interest in cluster randomised trials. Working with Professor Martin Bland, she wrote a series of statistics notes in the BMJ to provide researchers with accessible information and practical solutions to the issues of sample size and analysis.
She has collaborated on a number of randomised trials in primary care, both individually and cluster randomised. In 2000-4 she collaborated on a cluster randomised trial of an educational intervention to reduce blood pressure by reducing dietary salt in Ghana. In 2004 she published a systematic review of home blood pressure monitoring to improve blood pressure control and is currently PI a trial of home blood pressure monitors among stroke patients. This trial which is based at St. George’s is funded by The Stroke Association and due to be completed in December 2010.
Research interests:
Sally’s main research interests are in the design of pragmatic trials and improving the understanding and reporting of statistics among researchers. She has co-authored the book ‘Presenting Statistics from Proposal to Publication’ to help researchers clearly present statistics in peer review publications, theses and grant applications.
