Cluster randomized controlled trials.
Cluster randomized controlled trial (RCT), in which groups or clusters of individuals rather than individuals themselves are randomized, are increasingly common. Indeed, for the evaluation of certain types of intervention (such as those used in health promotion and educational interventions) a cluster randomized trial is virtually the only valid approach. However, cluster trials are generally m...
متن کاملBalance algorithm for cluster randomized trials
BACKGROUND Within cluster randomized trials no algorithms exist to generate a full enumeration of a block randomization, balancing for covariates across treatment arms. Furthermore, often for practical reasons multiple blocks are required to fully randomize a study, which may not have been well balanced within blocks. RESULTS We present a convenient and easy to use randomization tool to under...
متن کاملRandomized Clinical Trials in HFpEF
Heart Failure With Preserved Ejection Fraction Heart failure with preserved ejection fraction (HFpEF) or diastolic heart failure (HF) accounts for approximately half of HF cases in the community, and the portion of HF with preserved ejection fraction (EF) is increasing. Patients with HFpEF have limited functional capacity and poor prognosis. With ongoing shifts in the age distribution of the po...
