A benefit of randomized experiments is that covariate distributions of treatment and control
groups are balanced on average, resulting in simple unbiased estimators for treatment …

The multiphase optimization strategy (MOST) is an increasingly popular framework to
prepare, optimize, and evaluate multicomponent behavioral health interventions. Within this …

The present paper deals with the problem of designing randomized multiarm clinical trials
for treatment comparisons in order to achieve a suitable trade-off among inferential precision …

Objective To determine the effectiveness of a single session of prenatal motivational
interviewing (MI) to enhance breastfeeding outcomes. Design A randomized controlled trial …

In this study, it is aimed to develop a user-friendly open-source web-based software which
enables the assignment of the subjects included in the scientific research to the groups with …

It is known that clinical trials have potential risks for participants, which could result in
unexpected adverse events. To quantify and predict the risk of adverse outcomes, we …

A key role in inference is played by randomization, which has been extensively used in
clinical trials designs. Randomization is primarily intended to prevent the source of bias in …

This research estimated the pathogenic exposure levels and associated baseline bio-risks
in edible terrestrial snails (Achachatina marginata) sold in the Nigerian markets in an …

The random allocation of patients to treatments is a crucial step in the design and conduct of
a randomized controlled trial. For this purpose, a variety of randomization procedures is …

We present an optimized rerandomization design procedure for a non-sequential treatment-
control experiment. Randomized experiments are the gold standard for finding causal effects …
