Published in 2018 at "International journal of epidemiology"

DOI: 10.1093/ije/dyy057

Abstract: Background: Cluster randomised trials (CRTs) are increasingly used to assess the effectiveness of health interventions. Three main analysis approaches are: cluster-level analyses, mixed-models and generalized estimating equations (GEEs). Mixed models and GEEs can lead to… read more here.

Published in 2022 at "Clinical Trials"

DOI: 10.1177/17407745221087465

Abstract: Trial designs using cluster-level randomization are necessary when interventions have intended effects that cannot be measured with individual randomization. When an intervention is intrinsically only able to be delivered to a cluster or when implementation… read more here.

Published in 2021 at "Frontiers in Public Health"

DOI: 10.3389/fpubh.2021.799536

Abstract: Background To date, there is a lack of sufficient evidence on the type of clusters in which severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is most likely to spread. Notably, the differences between cluster-level and… read more here.
