Standard analyses of cluster randomised trials (CRTs) assume between-cluster independence. This assumption is potentially violated in CRTs against infectious diseases, whose clusters are often defined geographically, which potentially induces spatial correlation and indirect effects. This paper describes ...

Interventions based in the community can be evaluated by randomising clusters, such as general practices, rather than individuals, as in conventional randomised trials. This increases the sample size needed because of intracluster correlation. To estimate sample size requirements for cluster randomised tri...
Cluster Randomised Trials, Second Editionthoroughly describes the aspects of CRT designs and the analysis of data from such trials. After presenting some basic concepts, Hayes and Moulton focus on the clustering aspect of the design. They cover between- and within-cluster variability and correlation,...
Cluster randomisedtrials are trials in which groups (or clusters) of individuals are randomly allocated to different forms of treatment. In health care, these trials often compare different ways of managing a disease or promoting healthy living, in contrast to conventional randomised trials which rando...

Mathematical modelling and the HIV Prevention Trials Network (HPTN) 052 trial results suggest that universal HIV testing combined with immediate antiretroviral treatment (ART) should substantially reduce incidence and may eliminate HIV as a public health problem. We describe the rationale and design of ...
