- Don't know, can't know: embracing deeper uncertainties when analysing risksDavid J Spiegelhalter
Statistical Laboratory, Centre for Mathematical Sciences, Wilberforce Road, Cambridge CB3 0WB, UK
Philos Transact A Math Phys Eng Sci 369:4730-50. 2011..We conclude that the contingent nature of risk-modelling needs to be explicitly acknowledged in advice given to policy-makers, and that unconditional expressions of uncertainty remain an aspiration...
- Visualizing uncertainty about the futureDavid Spiegelhalter
Centre for Mathematical Sciences, University of Cambridge, Cambridge CB3 0WB, UK
Science 333:1393-400. 2011..Nonetheless, communicating deeper uncertainties resulting from incomplete or disputed knowledge--or from essential indeterminacy about the future--remains a challenge...
- Do increases in physical activity encourage positive beliefs about further change in the ProActive cohort?Wendy Hardeman
Department of Public Health and Primary Care, Institute of Public Health, University of Cambridge, Cambridge CB2 0SR, UK
Psychol Health 26:899-914. 2011..Future studies could test the effect of such techniques on physical activity and a wider range of cognitive, affective and physiological consequences, using more frequent measurement intervals...

J Pharmacokinet Pharmacodyn 36:19-38. 2009..This is in contrast to standard two-stage approaches whereby 'plug-in' point estimates for either the population or the individual-specific PK parameters are required...
- Allowing for correlations between correlations in random-effects meta-analysis of correlation matricesA Toby Prevost
General Practice and Primary Care Research Unit, University of Cambridge, Institute of Public Health, Cambridge United Kingdom
Psychol Methods 12:434-50. 2007..Because of potential instability in the generalized least squares methods, they recommend a model-based approach, either the maximum marginal likelihood approach or a full Bayesian analysis...
- Efficacy of a theory-based behavioural intervention to increase physical activity in an at-risk group in primary care (ProActive UK): a randomised trialAnn Louise Kinmonth
General Practice and Primary Care Research Unit, Department of Public Health and Primary Care, University of Cambridge, UK
Lancet 371:41-8. 2008..Efforts to reverse this trend have not been successful. We aimed to assess the efficacy of a facilitated behavioural intervention to increase the physical activity of sedentary individuals at familial risk of diabetes...
- Components of variance in a multicentre functional MRI study and implications for calculation of statistical powerJohn Suckling
Brain Mapping Unit, Department of Psychiatry, University of Cambridge, Cambridge, United Kingdom
Hum Brain Mapp 29:1111-22. 2008..Thus, theoretical models of power and empirical data indicate that between-centre variability can be small enough to encourage multicentre designs without major compensatory increases in sample size...

General Practice and Primary Care Research Unit, Department of Public Health and Primary Care, Institute of Public Health, Forvie Site, Robinson Way, Cambridge CB2 2SR, UK
BMC Public Health 4:48. 2004..While previous evaluations of interventions to increase physical activity have involved communities or individuals with established disease, less attention has been given to interventions for individuals at risk of disease...
